Unfortunately I am attached to the VTK binaries - I am responsible for a
very tiny piece of a larger project and surely the project is not going to
want to change their structure.

This is the mesa I have installed:
mesa-libOSMesa-7.6-0.1.fc11.i586

The libGL.so that VTK had for OPENGL_gl_LIBRARY was /usr/lib/libGL.so which
I imagine came with Fedora 11.

I changed OPENGL_gl_LIBRARY to /usr/lib/libGL.so.190.53 (this file was
presumably installed when I installed the NVidia 190.53 driver) and rebuilt
VTK. There was no change, wxVTKRenderWindowInteractor.py still segfaults.
Would I need to rebuild wxWidgets and wxPython to tell them to use this
190.53 libGL also?

Thanks,

David
