For those wanting an implementation of Python 2.7 with a Just-In-Time compiler in EPEL, I've built PyPy, for EPEL 5 and EPEL 6: * https://admin.fedoraproject.org/updates/pypy-1.7-3.el5 * https://admin.fedoraproject.org/updates/pypy-1.7-3.el6
I haven't tested them yet. [am in the middle of firefighting another issue, but I saw that the builds ran to completion; there were some test failures in the logs, but the great majority of the selftest suite passed].
So if you're feeling adventurous, please try these builds out (and give karma to the update accordingly).
Note that this is *not* an official Red Hat-supported thing, and that I intend to rebase pypy in EPEL to later versions after upstream releases them.
