DIBS: Distributed Internet Backup System

Hi all,
after setup dibs 0.93 under SuSE 10.0 I always get the following error message:

What is Tkinter, it seems that I have to install something more, but what?
I meanwhile installed:
python 2.4.1(default by SuSE 10.0)
python_devel
python_tk

Thanks a lot
Achim
