@jvlcek It turns out I can't do this without rewriting some of the gem.  Basically, there are calls to check for the bugzilla executable to verify python-bugzilla is installed, and changing it to just "bugzilla" causes those checks to not work properly.  I could rework the whole thing to have a python_bugzilla_installed? method, but that method would just call out to `which` anyway, so it would be kind of pointless for a trivial change.
