I think you may have misunderstood Jeff. Python 2.0 is the minimum
version needed for biopython. I use biopython with 2.0, 2.1 and
2.2pre-releases (depending on how lazy I am at updating the python
the machine), and everything works fine. 

The regression tests sometimes report problems between different
python versions and on different architectures (and in different
phases of the moon :-), and we try to take care of these when they
are noticed. If you run a test itself (ie. python test_Whatever.py),
then it should work fine, but the regression comparison with the old
output is what will fail.

We do our best to keep these up to date, but I know I have been
especially slack in working on this recently due to the excessive
amount of lab work I've had to do.
