Not necessarily -- 2.1 will install in lib/python2, so an older
xml package in site-packages would override the newer one from 2.1!

It seems we may have to start thinking about a package versioning

They can use $PYTHONPATH.

That's another possibility.  But then distutils will have to become
aware of package versions again.
