So the problem was that the line

> cd /tmp/buildd/paraview-3.2.1/obj-x86_64-linux-gnu/Utilities/VTKPythonWrapping/paraview
> && compile_all_pv.py

should be

> cd /tmp/buildd/paraview-3.2.1/obj-x86_64-linux-gnu/Utilities/VTKPythonWrapping/paraview
> && python2.5 compile_all_pv.py

And this can be accomplished by this simple patch:

$ cat debian/patches/python.patch

It is already applied in our svn repository, so all is fine now.
