I know this is a bug in python-vtk #529961, but mayavi2 loads on my
system without any problem. I don't know how you are getting this
import error from mayavi2. Can you check if you are able to "import
vtk" from a python shell. Looking at line 461 in /usr/bin/mayavi2,
this exception is caused by failure to import vtk, which shouldn't
happen.

Thanks,
Varun

p.s. If nothing helps, you may try to reset PYTHONPATH (as suggested
in 529961):
PYTHONPATH=$PYTHONPATH:/usr/lib/python-support/python-vtk/python2.5/vtk
