That's what I did too. I didn't investigate any further to understand 
why it happens...

You have to link against /usr/X11R6/lib/libGLU.1.3.dylib and 
/usr/X11R6/lib/libGL.1.2.dylib, which are part of Apple's X11.
You can get a list of all the libs I have linked against by running 
otool -L gnubg on the command line.

I don't get these warnings on my Powerbook G4 12", and I don't know 
what should happen on  a G5. When do you get the warnings? At startup?
The problem is that I don't know which parts of 3D drawing/acceleration 
are handled by GNU/Fink software or by Apple X11/Aqua software. Maybe 
Jonathan can tell us more about this...
Here are the figures I get on my laptop:
- standard drawing with shadows: 16 fps
- standard drawing without shadows: 33 fps
- quick drawing: 420 fps


Let me know if you need more info about how to build your own gnubg.

Best
