Hi Grobian,

well, to be honest, I'm not deep into this either. "osmesa.h" declares
functions in /usr/X11R6/lib/libOSMesa.dylib, which is not currently
included in apple-opengl, so it wouldn't really change something if we
omitted it. Both header and library are not part of the OpenGL standard
and but provide additional functionality (offscreen rendering).

Mesa is an OpenGL implementation doing rendering in software or through
DRI, which is Linux specific. It's most useful on platforms that don't
come with a native OpenGL implementation. On other platforms it's likley
only useful for developers.

However, since the ebuild is already in prefix and I was currently in
the need of having Mesa on my box, I have now an ebuild with Darwin
compatiblity modifications and would happily contribute it. ;)

Br,
Dirk.
