Thanks for your reply. For unknown reasons "dot" is missing. Could you
please tell me what package includes it?

Thanks

That's an interesting problem, haven't seen it with the Graphviz
installations that I use. I'm wondering if there's a problem of some
sort with launching graphviz programs (dot, neato, etc) from Python's
os.popen3 call.

Are you able to run the graphviz programs from a command line? What
version of graphviz are you running? (dot -V)

I currently don't have a Fedora system installed. Let me create Fedora
installation and see if there's anything that jumps out...
