do require 'yaml' before that line and see what happens.

It is a shot in the dark, but sometimes that fixes it.

I'm sorry I'm an idiot. When you see this you have to declare it in environment.rb. The problem is that in rails 3 it doesn't know about that constant. Hope this still isn't an actual issue.
