most of the bots are running 2.5.2, because that's the system python version
(Debian lenny).  I don't have any control over the O/S version, so I would
have to install a more recent python version locally.  Personally I think it
is wise to have buildbots running on older systems, since I reckon that there
are many people running oldish systems out there.  Lenny came out in 2009, and
was the latest stable Debian release until 6 months ago, so it's not even that
old.

What is the reason for upgrading?  Is there a problem with python 2.4/2.5 that
can't be worked around?

Ciao, Duncan.
