Hi,

        I'm trying to compile some examples from GEANT4 (from Cern)
using the opengl visualization driver (X Windows) version.
        The program compile fine but fail to link, giving me the
messages:

[...]

        I have a NVidia TNT2 M64 card installed and working fine; have
xlibmesa3, xlibmesa-dev, xlibosmesa3, xlibosmesa-dev installed as well
nvidia-glx nvidia-glx-dev.
        Any help,
