mod_shib_24 fails to load after upgrade

Actually, that can't be it, because libsaml used to be linked to zlib, so it has to have been there from the older version. It's the same dependency, it just moved down a library from one to the other. I have no idea what it could be but I'll still check and see what the rpm commands say.

It's not finding zlib, which would suggest the build didn't pull it in as an RPM requirement so the working machines have it and the non-working ones don't. I don't have enough understanding of RPM to know why it wouldn't have identified it as a runtime requirement but I know enough to run the queries and verify what it did so I can verify what it thinks it needs.

If zlib isn't there, I assume installing zlib would address it, because there's no way it could work on any box otherwise and it worked fine on mine.
