Both orderings have their problems, maybe the situation of local python
installations should be rethought.

What I mean is that you can have a source package with
Build-Depends: python-dev (>= 2.1)
which generates binary packages with
Depends: python (>= 2.2), python (<< 2.3)
or
Depends: python (>= 2.3), python (<< 2.4)
etc. depending on the current python version installed on the building
machine.
In this case, the strict build dependency on python-dev (>= 2.3) is only
here to ensure the autobuilder has the right version installed.
Is this more clear?

Sounds reasonable.
