This might be a Tcl/Tk version issue.  Try these:

   ldd  /data/vtk4.0/VTK/bin/libvtkRenderingPythonTkWidgets.so

   ldd /data/ASD_work/cdat/lib/python2.2/lib-dynload/_tkinter.so

And make sure they both point to the same version of libtcl*.so and
libtk*.so.

If they don't then recompile VTK with the libtcl and libtk pointing to
the same libtcl/tk that your Python's _tkinter.so points to.  This
might fix your problem.

Good luck!

cheers,
