Bug description:
Hi!
I recently sucesfully installed dorsal, but I can not use Viper in ipython. My problem is very similar to that relating to Question #102151 but there seem not to be a similar solution. I have tried to reinstall vtk-devel and then dorsal, but have not been succesfull. 

The following is my output when trying to import viper in ipython.

In [2]: import viper
------------------------------------------------------------
Traceback (most recent call last):
  File "<ipython console>", line 1, in <module>
  File "/Users/tor/Work/FEniCS/lib/python2.6/site-packages/viper/__init__.py", line 23, in <module>
    from viper import *
  File "/Users/tor/Work/FEniCS/lib/python2.6/site-packages/viper/viper.py", line 48, in <module>
    import vtk, numpy, os, math
ImportError: No module named vtk

Any Ideas?
Thank you!
