Actually it can also happen in your source tree if you pull or merge,
because the xml.pyc will still be there.  (Python sucks sometimes.)

distutils doesn't have an 'uninstall', but if it did it probably
wouldn't help a lot because we need to uninstall the old version.

What we probably want, and what might be possible, is to delete
everything inside the installed bzrlib pacakge (but not bzrlib.plugins)
before installing.

If you install from a .deb or similar package it's fine.
