I'm no MySQL expert, but from the error message it looks to me as tho' the versions of your MySQL client and server libraries are mismatched. You're running version 9 on the client and version 10 on the server. Maybe your recent upgrades weren't as successful as you thought, or maybe when you built and installed DBD::mysql, it picked up an older version of the library.
