> On RHEL 5, which I guess we still want to support, the default "python" in the path is still 2.4. cqlsh does use a fair number of python features introduced in 2.5, like collections.defaultdict, functools.partial, generators. We can require RHEL 5 users to install a later python from EPEL, but we'd have to call it as 'python2.5', or 'python2.6', etc.
> So rather than take the time to vet everything against python2.4, we may want to make a wrapper script for cqlsh that checks for the existence of python2.7, 2.6, and 2.5, and calls the appropriate one to run the real cqlsh.
