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.
