No indeed, I'm always glad to hear that other people are using
VTK+Python.  More power to us.

Odd.  For me the fix works universally (but, again, shouldn't be
necessary in the first place).

The python stuff will require a manual install for some time to come,
though I will be updating the README.python file to assist with this.
For myself, I never actually do a 'make install' because I always
have two versions of VTK going at once, and switch between them
by setting the LD_LIBRARY_PATH and PYTHONPATH.

The vtkRenderWidget is very new -- expect minor changes before 3.0 comes
out.   You want to load vtkRenderWidget.py, which is a python wrapper
for the vtkTkRenderWidget (which is a Tk extension module).  If you
use Tkinter, you'll want to try it.
