which pkgs to get glchess in 3D ?

[Luca Dionisi]

Hi

In my system, intel G965, accelerated 3D works well.
But...
when I try to view glchess in 3D I get always this message:

Your system does not have the required software to enable 3D mode.
Please contact your system administrator and ask them to install the
OpenGL Python bindings and the GtkGLExt Python bindings.

I haven't found yet what the packages to install are.

Anyone?
