Ah.... that sparked a memory.

I actually had a lot of trouble with the machine overheating last  
summer, and the only way I could get it to start properly was to  
disable the following kernel extensions...

   drwxr-xr-x    3 root  wheel   102 Oct 11  2007 GeForce.kext
   drwxr-xr-x    3 root  wheel   102 Oct 11  2007  
GeForce2MXGLDriver.bundle
   drwxr-xr-x    3 root  wheel   102 Oct 11  2007  
GeForce3GLDriver.bundle
   drwxr-xr-x    3 root  wheel   102 Oct 11  2007  
GeForceFXGLDriver.bundle
   drwxr-xr-x    3 root  wheel   102 Oct 11  2007 GeForceGA.plugin
   drwxr-xr-x    3 root  wheel   102 Oct 11  2007 GeForceVADriver.bundle

I've re-enabled them and looks to be working now - thanks!  Wierd  
thing is that other opengl apps still work with these disabled. I  
guess the AGL falls back to some sort of compatibility mode if it  
can't find the drivers, and pyglet doesn't by default find these  
configs ?

Cheers,

A.
