Pragmatically, I would go with 2.6 as a floor.  The changes in 2.4 → 2.5
and 2.5 → 2.6 are such that I think it worth saying goodbye to 2.4 and
2.5 -- and removing all the code in SCons that is to do with replicating
features from later versions of Python to handle earlier versions of
Python.

The question that really needs to be answered is which version of Python
are people who actually use SCons using to run SCons. At the moment we
are talking about RHEL and their inability to upgrade, but are the vast
majority of SCons users using RHEL?  I suspect not.  Whatever version is
being discussed on the Python list does this affect people who are
running SCons. I suspect not, at least not directly.

If 80% of SCons users are on 2.4 or 2.5 and will be for > 2 years then
clearly 2.4 has to be the floor.  If 30% of people are using Python
earlier than 2.6 and everyone else is on 2.6 and later then switching to
a SCons floor of 2.6 clearly makes sense.

As Number 5 said:  "Input, input"

Philosophizing in the presence of little user data doesn't really make
any sense.
