Hm, I don't know MacOS X nor IRIX, but if they have libGL.so as well it
should be easy:
Just check if libGL.so exists somewhere in the library path and use
that one if so, otherwise build MesaLib.

Hm, an OpenGL meta pkg would be also an idea. You could select which
framework to use with the PKG_OPTIONS. Then simply a dependency on the
real framework is made, and on X11 it's just another empty pkg. I guess
that would be even better than having gl.mk :)
