[vtkusers] Python and VTK under Linux

[David Gobbi]

Hi Brian,

It looks like the python header files that you compiled against
might not match the version of python that you are running.  Bring
CMakeCache.txt into a text editor and make sure that all the python
variables are pointing to the correct locations.
Also, make sure that BUILD_SHARED_LIBS:BOOL=ON
