You really don't want to use Python 2.4 unless you have to. The modules
for it are getting more and more unmaintained due to nobody using them,
and we're trying to update all its dependents so we can just remove it.

There's no py26-biggles at present, but it could probably easily be
created from the py25- version. I know py26-pyobjc builds fine.
