Some of the bizarre behavior I see is that ./configure will succeed with
no fatal errors but upon building the first thing it complains about is
that the math functions are redefined (acos, atan, asin etc). Wondering
if you see this behavior or not? (I actually commented the redefinitions
out of config.h).

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

It later fails during linking with an enormous number
of undefined references to glut/gl among other things.

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.

Do you know if hardware
acceleration for 3d is supported on the new G5's? Gnubg complains that
the hardware is not supported for 3d acceleration and performance may be
slow (and tosses up a couple warning boxes).

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.
