This is inaccurate. A python2.7-minimal pre-depends on python-minimal
ensures that python-minimal is unpackaged _and configured_ before
python2.7-minimal is unpacked. If you don't need python-minimal to be
configured before python2.7-minimal is unpacked, a regular dependency is
what you want.

A regular dependency will also ensure that python-minimal is configured
before python2.7-minimal is configured.

So I don't see the need for a pre-depends?
