rollback yum update for a single package?

[Alec O'Neill]

Thanks for your feedback, Chet.

Looks like none of the old RPMs are available anymore.  

The environment is an undocumented bunch of small boxes, most of them running some web environment on top of RHEL ranging from 2.1 to 5.1.  No two boxes are the same.

Unless someone knows how to rebuild packages based on the binaries on the system, I guess I'll just have to risk it.

Thanks,

Alec
