Well, binding to a so specific version is not very elegant...

In centOS, argparse is back-ported to python 2.6, and it lives in a
separate package called python-argparse, AFAIK. I suspect it is also
back-ported to RHEL6's python 2.6, did you search for it?

Here:

they suggest to bring argparse via pip, which is in my opinion a good
enough way. I often bring something useful from PyPI, because not all
the cool and widely-used Python stuff is packaged in distributions.
