It didn't come with the distribution, I installed it via apt-get. Is anyone else getting an error like this?

Exactly, 1.8.3 was released on 09/21/2005. Somebody took a development
snapshot instead of taking critical patches and declared it the ruby to be
used in Ubuntu Breezy. The people who noticed the version were a bit too late
and Breezy had already been frozen.

Have you got Rails installed? It does some monkeypatching to class
Logger. Its aimed at the standard logger, but since neither Logger nor
Log4r are namespaced, and they both are class Logger, it effectively
breaks Log4r.

I think.
