[vtkusers] Problem VTK4 + python 2.2

[Emmanuel Olart]

Right it also works for me when setting my PYTHONPATH and my 
LD_LIBRARY_PATH to the path where i built VTK

export PYTHONPATH=$VTKSRC/Wrapping/python:$VTKSRC/bin
export LD_LIBRARY_PATH=$VTKSRC/bin

but as prabbhu wrote, if my LD_LIBRARY_PATH points also to 
/usr/local/lib/vtk it doesn t work anymore ...

I think maybe the make install did something odd with the path?

Souldn t the python wrappers be copied somewhere else ?

Regards

Emmanuel
