Hm, I think I do #include <OpenGL/OpenGL.h> instead. Which is the OpenGL
framework include (I don't have my Mac near, so can't check for the
exact name).
At link time, add '-framework OpenGL' to the link line.

Strange; just a ranlib on the lib*.a files works for me here
(OSX10.2.3).

This should probably be unnecessary if you link with g++. The above
looks like you're linking with gcc instead of g++.

Ah, I don't run in X11 though (haven't used DrawStuff on Mac as well,
just on Linux).

Hopefully someone can fix this in the CVS.
