Only makes sense on Linux, so you don't need this.

This looks wrong (or at least incomplete). The Wrapping/Python directory
is where the sources for the wrappers get created.

Try inspecting sys.path from vtkpython. I suspect there is another
directory you are missing in your PYTHONPATH.

The module is 'vtk', not 'vtkpython'.

You probably have a space in your path? Hard to tell where this is
coming from. Try running `bash -x` to see what the command line causing
this is. That should make it easier to find.
