Very tempting suggestion...

I installed my vtk-devel as adviced in dorsal - and the same way that worked
for Aron, vtk-devel +python26. This gives:

    $ port installed vtk-devel
  vtk-devel @5.4.2_1+cocoa+data+doc+examples+python26+shared+testing
(active)

However I am now trying to install vtk-devel +py26, to see if there is any
improvement. I have an other issue which might be  related, and I do not
know how to fix. I can not 'import Scientific' in python. I have
python-scientific installed via macport, and a reinstallation does not help.
Any easy fix, or is it maybe related?

I get a quite substantial output when running:

     $ port variants vtk-devel
vtk-devel has the variants:

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!
