[solved]Screwed graphics

[Gert]

I kind of have the same problem with the graphics of Penumbra Overture V 1.0.2553

"ldd penumbra.bin" says regarding GL stuff:
libGL.so.1 => /usr/lib32/opengl/ati/lib/libGL.so.1 (0xf7e20000)
libGLU.so.1 => /usr/lib32/libGLU.so.1 (0xf7d9f000)
libCg.so => not found
libCgGL.so => not found
(In addition the libfltk.so.1.1 is also missing.)
As you can see I have a ATI Graphics card and its drivers don't provide the CG libraries.

Specifically, I have

Card: Radeon HD 4850
Driver: 9.6 (8.62.4)
OpenGL-Version: 2.1.8673
Linux: 2.6.28-gentoo-r5 amd64

Peeking at the ATI -Windows forum I tried to turn off the driver AI, but it didn't change anything.
I've attached the log.

Many thanks,

Gert
