I have included a changeset which checks for Apple's OpenGL framework. But this 
is not the only change that is needed, I also needed to add $(OPENGL_LIBS) into 
src/Makefile.in line 277 OCTINTERP_LINK_DEPS. I am not sure if this is the right 
place, but liboctinterp.dylib can be created now. If yes, then I can send 
another changeset for this?
