MacOS X, Linux, Win32, at least. Probably anything with an OpenGL 
library.

Make sure your OpenGL is working in other apps, e.g. glxgears. Use ldd 
to find out which library it is actually linked against (should be 
/usr/lib/libGL.so.1). Make sure /usr/lib/libGL.so is a symlink to that 
library. Make sure you have the Squeak B3DAcceleratorPlugin.

Well, nobody is seriously working with the Balloon3D engine anymore. 
But you surely could employ Takashi Yamamiya's ODE plugin 
(http://languagegame.org:8080/ggame/15). We used it successfully with 
Croquet.
