Upgrading python-policy-spf

Is there any convenient way of upgrading python-policy-spf for Postfix?
I tried simply running the Python installer over the top of the existing
install but the man files didn't get updated, so it seemed a bit faulty.
There isn't an RPM package for RHEL 4, so unfortunately I can't take
that easy option. I did a slash-and-burn of the existing components,
since Python doesn't provide a package uninstaller, and re-ran the
install, but would like to avoid doing that again if possible.

TIA.
