[vtkusers] vtk python

[Edward Hartley]

hi
I've built VTK with the Python wrapper enabled
the build proceeds satisfactorily.
I've installed the vtk wrappers in my site-packages directory
and the VTK4.2.1 directory is in my PYTHONPATH
However
python
 >>>import vtk
produces

Import Error /usr/local/packages/VTK4.2.1/bin/libvtkComon.so:
undefined symbol: __tiostream

I built with CMAKE linker flag -L/usr/lib -llibstdc++-3-libc6.2.2.10.0
which nm shows has this symbol

I would welcome any suggestions.
Regards
Ed Hartley
