Sarge shipped a very different Python environment. Your chances of getting
a Python package to work on both Sarge and Hardy are just about nil. Sarge
is no longer supported by Debian and so it's really past time to move to
Etch in any case. With releases with reasonably modern pysupport (all
supported Debian/Ubuntu releases except Ubuntu Dapper) this is achievable
with a single source package, but you will likely have to (and should in
any case) build a binary on the target toolchain for each release you want
to support.

The problem here is that your package says it needs Python 2.4 and Sarge
has only 2.3. This is expected. If your package works with 2.3, then
change pyversions (noting again that Sarge is no longer supported by
Debian).

Give up on Sarge is my advice. If you can't, don't use pysupport. Use
dh_python and do it that way for Sarge/Dapper.
