        Even without the --with-qt option, you can display native VTK render windows
        from python. Alternatively, you can integrate the RenderWindowInteractor
        in PyQt, PySide, Tk or Wx at runtime. Read more:
            import vtk.qt4; help(vtk.qt4) or import vtk.wx; help(vtk.wx)

        VTK5 is keg only in favor of VTK6. Add
            #{opt_prefix}/lib/python2.7/site-packages
        to your PYTHONPATH before using the python bindings.
