Indeed, we have two packages called =E2=80=9Cpython-wrapper=E2=80=9D, a mis=
take from
95288fc.

This is fixed with:

However, this entails a big rebuild, so this will have to go to
=E2=80=98core-updates=E2=80=99.

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 =E2=80=98python-minimal-wrapper=E2=80=99 private.

Thoughts?

Ludo=E2=80=99.
