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

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... - Peter _______________________________________________ Trac mailing list [email protected] http://lists.edgewall.com/mailman/listinfo/trac
