Be careful suggesting that people upgrade, at least until you have
found out that they aren't running CentOS enterprise edition. The
CentOS packaging system is utterly dependent on having the Python
version it expects, and if you install a more recent version
(from source, say) the whole packaging system will stop working.
Recovering from this problem is also very, very difficult (unless
you just restore from a recent full backup).
Been there, done that. :(
