Yes, you need to put the Wrapping/Python and the bin directories in
your PYTHONPATH.

    PS> % setenv PYTHONPATH
    PS> "/scr1/psh/Python-2.2/lib/python2.2:/scr1/psh/vtk/VTK/Wrapping/Python:/\scr1/psh/vtk/VTK/bin"

That does not look correct (I hope its a typo), it should read:

setenv PYTHONPATH "/scr1/psh/Python-2.2/lib/python2.2:/scr1/psh/vtk/VTK/Wrapping/Python:/scr1/psh/vtk/VTK/bin"

Thats strange.  What options did you set in the CMakeCache.txt.  Here
is a part of my setup:

----------
//Where can one of the python, python21_d or python20_d libraries
// be found
PYTHON_DEBUG_LIBRARY:FILEPATH=

//What is the path where the file Python.h can be found
PYTHON_INCLUDE_PATH:PATH=/usr/local/include/python2.1

//Where can one of the python, python21, python2.1, python20 or
// python2.0 libraries be found
PYTHON_LIBRARY:FILEPATH=
----------

Note that I don't explicitly set a PYTHON_LIBRARY.  I've run into
problems earlier when I did link to libpython*.a

Hope this helpsm
