Indeed, we have two packages called “python-wrapper”, a mistake from
95288fc.

This is fixed with:

However, this entails a big rebuild, so this will have to go to
‘core-updates’.

In the meantime, I would recommend using -e to unambiguously refer to
the right wrapper.  Otherwise, we could come up with workarounds, such
as keeping the ‘python-minimal-wrapper’ private.

Thoughts?
