[xcrysden] [Partially solved] Install fails at startup in function glLightfv()

[Lucas Fernandez Seivane]

The shared uses system version of mesa, opengl tcl/tk and all that,
the semi-shared used some inside but relies on system tcl. I think
again of a bug of the kernel. Usually, I install the semi-shared,
since it is less distro-dependent, and xcrysden is not packed by any
distribution.
