When trying to start celestia I get this:
Loading ARB vertex program: shaders/diffuse_arb.vp
Error loading ARB vertex program: shaders/diffuse_arb.vp
Initializing NV fragment programs . . .
Loading NV fragment program: shaders/shadow_on_rings_nv.fp
Error loading NV fragment program: shaders/shadow_on_rings_nv.fp
celestia is looking for the shaders in /usr/share/celestia/shaders but the
individual shader files are in /usr/share/celestia. If I move the shaders to
the correct location by hand it still crashes because of the same issue with
textures, models, and everything else. If I move everything by hand it starts
fine.
