894480 - remove PyXML dependency

Quote from BZ:
I've opened up a Fedora 19 Feature to remove PyXML due to a combination of it being dead upstream for many years and that when it's installed, the python stdlib overwrites its own xml module with PyXML.  This combination leads to errors because PyXML's code is older and contains bugs that have been fixed in the stdlib.
