 From my experience, they can both be installed, but you can't have both 
paraview's vtk libraries and the independent vtk libraries in 
$PYTHONPATH and $DYLD_LIBRARY_PATH. You are probably adding the paraview 
ones somehow before you run your script. If you don't do that, then the 
independent vtk libraries should be loaded and should work OK.
