That's a bit of a workaround though.

Ideally Zope2 should be an egg which somehow tells buildout/setuptools
that it also provides the various zope.* packages it includes at the
moment. Similar to the providers-mechanism which packaging systems like
dpkg and rpm implement perhaps. Provides and (semi-) virtual packages
are going to be essential to deal with swappable components as well.
