While here, clean up some unrecognized configure arguments
and fix the build with the qt4 option.
XXX: this supports qt5 now too, does someone want to add an option for that?

might incur ncurses dependencies on some platforms, and ncurses just bumped

Some packages were bumped twice now, sorry for that.

NOTABLE NEW FEATURES IN VERSION 5.0.1
=====================================
Incremental releases 5.0.1, 5.0.2, etc are primarily intended to provide bug
fixes, but 5.0.1 also contains several adjustments resulting from feedback on
changes and new features in version 5. The most notable is addition of a new
command "set monochrome" that allows emulation of the terminal-specific "mono"
option that was lost in version 5. The new commands "set mono" and "set color"
switch between two parallel sets of default linetypes. Six monochrome
linetypes are pre-defined; these can be altered or new ones added using the
command "set monochrome linetype N <line-properties>". Although these do not
exactly duplicate those of any particular pre-version 5 terminal, approximate
backwards compatibility is provided by automatically switching to the
monochrome linetypes if the "mono" keyword is present in "set term".
I.e., "set term pdf mono" is equivalent to "set term pdf; set mono".

- Two targets added, post-build: and post-install:,
to build gnuplot.pdf (which was in 4.6.6 PLIST),
and two dependency for above process. Thanks gdt@ for comment.

---------------------
GNUPLOT Version 5.0 Release Notes
=================================
Gnuplot version 5 contains significant new capabilities and enhancements.
The most recent previous release was 4.6 patchlevel 6 (4.6.6).
Please see the NEWS file for bugfixes and minor changes to version 5.0
applied after feedback on release candidates -rc1, -rc2, and -rc3.
Release Notes date: 31 December 2014
NOTABLE NEW FEATURES
====================
* New plot styles "with parallelaxes" and labeled contours.
* New coordinate system (Degrees, Minutes, Seconds) "set xdata geographic".
* The "fit" command can now handle functions with up to 12 variables, and
can take into account errors on x as well as errors on dependent variables.
Final covariance terms are stored in user-accessible variables.
Fitting options are now controlled by the command "set fit ..." rather than
by environmental variables.
* The interpretation of columns in a "fit" command depends on new keywords
"error", "xyerror", "zerror". In most cases the program can also recognize
version 4 syntax (no error keyword but last column contains zerror).
* The dot/dash pattern of a line can now be controlled independently
from other line properties using the keyword "dashtype".
* The default color of individual line types can be changed using
"set linetype" (introduced in 4.6). In version 5 a default overall color
sequence can be selected using "set colors {default|classic|podo}".
The "classic" sequence is red/green/blue/magenta/cyan/yellow as used by
older gnuplot versions. The default and podo colors are chosen to be
more easily distinguished in print and in particular by people with color
vision problems.
* Text markup now supports bold and italic font settings in addition to
the subscript, superscript, font size and other options previously
provided by the "enhanced text" mode. This mode is now the default.
* Command scripts may place in-line data in a named data block for
repeated plotting.
* Bit shift operators << and >>
* RGB colors can include an alpha-channel for transparency.
# ARGBcolor = (Alpha << 24) + (Red << 16) + (Green << 8) + Blue
* Secondary axes (x2, y2) can be locked to the primary axis via a mapping
function. In the simplest case this guarantees that the primary and
secondary axis ranges are identical. In the general case it allows you
to define a non-linear axis, something that previously was only possible
for the special case of log scaling.
* The "import" command attaches a user-defined function name to a
function provided by an extenal shared object (i.e. a plugin library).
* Previous commands in the history list of an interactive session can be
reexecuted by number. For example "history !5" will reexecute the
command numbered 5 in the list reported by "history".
* Hypertext labels in the interactive terminals including web display
using the HTML canvas or svg terminals.
Many other additions are described in the "New Features" section of the
documentation.
CHANGES
=======
Gnuplot development assigns very high priority to backward compatibility
with earlier versions. For example any command script that worked in
version 4.0 is expected to continue to work for all version 4 releases
including the most recent one (4.6.6). However changes introduced in
version 5 can affect the operation of some version 4 scripts.
A brief summary of potentially incompatible changes is given here.
* Earlier versions of gnuplot used the keyword "linetype" to mean both
the color and the solid/dot/dash pattern of a line. Version 5 has
separate keywords "linecolor" and "dashtype". You can use these keywords
directly in a plot command or assign any desired color and a dash pattern
to a linetype. The program now provides a default set of 8 linetypes, all solid.
You can change these or add new linetypes as you please. You do not need
to change the current terminal or terminal mode in order to use dashed lines.
* The handling of input data containing NaN, Inf, an inconsistent number of
data columns, or other unexpected content has changed. See documentation
under "missing" for examples and figures.
* Time coordinates are stored internally as the number of seconds relative
to the standard unix epoch 1-Jan-1970. Earlier versions of gnuplot used
a different epoch internally (1-Jan-2000). This change resolves
inconsistencies introduced when time in seconds was generated externally.
The epoch convention used by a particular gnuplot installation can be
determined using the command `print strftime("%F",0)`.
Time is now stored to at least millisecond precision.
* The function `timecolumn(N,"timeformat")` now has 2 parameters.
Because the second parameter is not associated with any particular data axis,
this allows using the `timecolumn` function to read time data for reasons
other than specifying the x or y coordinate. Use of time formats
to generate axis tick labels is now controlled by "set {xy}tics time" rather
than by "set {xy}data time". Thus prior calls to `set xdata time` or
`set timefmt x` are unnecessary for either input or output.
These older commands still work, but are deprecated.
* The "reverse" keyword (e.g. "set xrange [*:*] reverse") now affects only
autoscaling. It has no effect on explicit ranges.
"set xrange [0:1] reverse" is _not_ the same as "set xrange [1:0]".
* Options to the "fit" command are now given by "set fit ..." rather than
by setting environmental variables. Fit can handle up to MAX_NUM_VAR
independent variables (currently 12). Variables other than the first
two (x, y) have been dissociated from axis names. This means, for example,
"set urange [U1:U2]" has no effect on fitting because "u" is not a fit
variable. Use the command "set dummy ..." to assign names to fit variables
3 ... 12.
* The `call` command is implemented by providing a set of variables ARGC,
ARG0, ..., ARG9. ARG0 holds the name of the script file being executed.
ARG1 to ARG9 are string variables and thus may either be referenced directly
or expanded as macros, e.g. @ARG1. The older convention for referencing
call parameters as tokens $0 ... $9 is deprecated.
* "unset xrange" (and other axis ranges) restores the default range.
* "unset terminal" restores the original terminal of the current session.
