Subject: Bootstrapping pkgsrc to build 64-bit binaries on Solaris with SunPro
 is non-trivial. At least, it's documented now.

+	<para>Building 64-bit binaries is a little trickier. First, you

+	that while building one of the programs in the bootstrap kit
+	(<filename>bmake</filename>), the <varname>CFLAGS</varname>
+	variable is not honored, even if it is set in the environment.
+	To work around this bug, you can create a simple shell script

+	<para>Packages that don't use the flags provided in the
