Hm, interesting. I do not get those errors, but when I did just see:

ERROR: In /home/doriad/src/VTK/Rendering/OpenGL/vtkShadowMapBakerPass.cxx,
line 277
vtkShadowMapBakerPass (0x96aa808): FBOs are not supported by the
context. Cannot use shadow mapping.

ERROR: In /home/doriad/src/VTK/Rendering/OpenGL/vtkShadowMapPass.cxx, line 186
vtkShadowMapPass (0x96aa858): FBOs are not supported by the context.
Cannot use shadow mapping.

Does anyone know how to get FBOs supported by the context :) ?
