Attached is my spec for func 0.0.13 for CentOS 4 and 5. I've built both of these today and have them in production.
The spec checks as clean with spectool.
The key dependency is python-setuptools, which I have in my engineering repository, but is in kb's extras for C4 and in EPEL5 (and probably a candidate to be moved into Centos Extras too).
Regards,
