py-wxpython-2.8 +gtk: missing gtk include path (-I${prefix}/include/gtk-2.0)

[mojca (Mojca Miklavec)]

Compilation of py2X-wxpython-2.8 fails because of missing include flags for gtk2:

OK, I believe I see the problem now. The file config.py contains:

    if sys.platform[:6] == "darwin":
    ...
    else:
        # Set flags for other Unix type platforms
        GENDIR = WXPORT

        if WXPORT == 'gtk':
            WXPLAT = '__WXGTK__'
            portcfg = os.popen('gtk-config --cflags', 'r').read()[:-1]
            BUILD_BASE = BUILD_BASE + '-' + WXPORT
        elif WXPORT == 'gtk2':
            WXPLAT = '__WXGTK__'
            GENDIR = 'gtk' # no code differences so use the same generated sources
            portcfg = os.popen('pkg-config gtk+-2.0 --cflags', 'r').read()[:-1]
...

and thus

pkg-config gtk+-2.0 --cflags

never gets executed.

Wrong observation, I already fixed that. After adding the missing pkgconfig dependency in r110414 the problem was solved.
