>Description:
x11/gtk2/patches/patch-ad replaces certain directory variables in
gtk/xdgmime/xdgmime.c with a define to pkgsrc's PREFIX directory.
x11/gtk2/Makefile then tries to define this variable by setting
it as a -D flag in CPPFLAGS.


Unfortunately, the definitions set up the Makefile are never propagated
to the command line and the build fails.

>How-To-Repeat:
Just try to build x11/gtk2.
It is possible that the problem is platform specific.
If so, try to build x11/gtk2 on OS X.

>Fix:
Altough the problem _might_ be OS X specific, the solution isn't.
Instead of trying to get the necessary define passed to the compiler
from the command line, include the definition in config.h.

Here's the patch against x11/gtk2/Makefile:
