Whence comes UnifiedRuby ? The Google, it does nothing!
Matt, I think there is supposed to be a lib directory bundled up in the gem, but it is not. (Did you get an error on install?) In that lib, I'm guessing there is a unified_ruby.rb.
In the meantime, I think you'll find that it seems to work if you comment out the require and include.
