Finally, I did spend those hours and found a workaround. It turns out 
that there are two incompatible declarations of glTexImage3D floating 
around in the various OpenGL/gl.h or GL/glext.h headers. Apple changed 
the OpenGL/gl.h header between OSX 10.6 and 10.7 from one version to the 
other, and vpython is now mixing the two, which does not compile.

Patching the definition of PFNGLTEXIMAGE3DEXTPROC in include/GL/glext.h 
allows visual to compile, and it runs OK.

Version 5.74 is now in Fink.
