1) fix the PLIST to correspond with the files added+removed
2) fix the interpreter in some installed files
3) ignore work-directory references in 12 installed files. Yes, this
is wrong, and has been reported to parrot, issue #201.
PKGREVISION not bumped, since this would not create a package earlier.

Pkgsrc changes:
o Remove local patch which is no longer needed.
o Adapt PLIST to changes in the set of installed files.
Upstream changes:
- Core
+ A new embedding API is available in "parrot/api.h" and documented in
docs/pdd/pdd10_embedding.pod .
+ Packfile PMCs were refactored and can now be used to produce runnable
bytecode.
+ Packfile manipulation code now throws embedder-friendly exceptions rather
than printing error details directly to stderr.
+ Unicode support for file IO, environment variables, program names, and
command-line parameters was improved.
+ An experimental gdb pretty-printers in tools/dev for Parrot STRINGs and
PMCs is now available. (gdb 7.2 or later and Python are required)
+ c2str.pl and pmc2c.pl improvements result in a noticeably faster build.
+ Bugs in our Digest::sha256 library and bit-related dynamic ops were fixed
by GCI student Nolan Lum. Both now work correctly on 32 and 64 bit
systems.
- Languages
+ ;)XD - OMeta for Winxed https://github.com/plobsing/ohm-eta-wink-kzd

+ HTML documentation generation has been rewritten and greatly simplified.
+ We have improved documentation in docs/project/git_workflow.pod about
keeping a fork of parrot.git in sync.
+ Translations of our README in various languages are now in the
docs/translation directory, thanks to Google Code-In students.
- Tests
+ A better way to write "todo" tests with Parrot's Test::More was implemented
by GCI student Fernando Brito.
+ Major increases in test coverage of many core PMCs, dynamic PMCs and
dynamic opcodes resulted from GCI and the intrepid students it attracted.
+ Jonathan "Duke" Leto set up Debian Linux x86_64 and sparc32 smokers
in the GCC Compile Farm, which continually submit smoke reports with
a variety of configuration options and compilers. Thanks, GCC!
+ Makefile dependency checking is now automatically tested, resulting in a
more reliable parallel build.
+ Coverage tests were improved for platforms with and without Devel::Cover.

t/op/inf_nan.t, t/op/literal.t, t/op/number.t, t/op/sprintf2.t,
and t/op/00ff-dos.t were converted to PIR.
