Looks like a problem with my VTK-Python bindings. I get

  >python2.4 -c "import viper; print viper.__file__"
  Traceback (most recent call last):
    File "<string>", line 1, in ?
    File "/usr/lib/python2.4/site-packages/viper/__init__.py", line 1, in ?
      from viper import *
    File "/usr/lib/python2.4/site-packages/viper/viper.py", line 10, in   ?
      import vtk
  ImportError: No module named vtk

My python-vtk package is for Python 2.5, whereas I'm using Python 2.4 
due to the SWIG bug. If I do

  python -c "import viper; print viper.__file__"

I get

  /usr/lib/python2.5/site-packages/viper/__init__.pyc
