Strange "camelize" error when running fresh rails install on Hoary

Hi everyone,

Just wondering if anyone had seen this before. I did a simple install
following Paul Goscicki's tutorial
(http://paulgoscicki.com/archives/2005/09/ruby-on-rails-on-ubuntu/) and
I get this message when I type "rails test" from the command line.(I'm
running Ubuntu 5.04 Hoary)

could anyone point me in the right direction? thanks.
