[vtkusers] import vtk,segmentation fault, python

[David Gobbi]

Hi Petr,

It's failing because it is trying to load vtkParallelPython.so from
/usr/lib64/paraview/, rather than from your own directory.  My guess
is that /usr/lib64/paraview is in your PYTHONPATH and you did
not build your own VTK with VTK_USE_PARALLEL=ON, so when
python can't find vtkParallelPython.so in your directory, it automatically
searches the PYTHONPATH and finds the one in /usr/lib64/paraview,
which was probably built for a different version of VTK.
