How I got it working in Fedora 13

You should be able to keep the provided "Cg" libs and just move the rest out of the way.. As the Cg is a Binary only library so it will be the same as the one provided by Nvidia (unless nvidia has something newer that like version 2.2 out)

Mmh it is something similar to what we've done for the pulse audio libraries? (Removing old libraries in the game to use newer in the Operating System)
