D'oh. I was afraid of that. Hopefully my hosting service will install the newer version for me.

I'm curious, how hard is it to install a module like DBD::mysql into a home directory? I have installed modules like this as root, but never as a normal user. And if my hosting service won't upgrade the module, I'll be forced to do it myself.

Anyways, thanks for your help! It's nice to know that I wasn't the cause of the problem.
