I am following this tutorial  
[http://www.aidanf.net/rails\_user\_authentication\_tutorial](http://www.aidanf.net/rails_user_authentication_tutorial)  
to create a basic user auth system, but when I try and run the test I  
get a slew of errors with rails:

d:/ruby/lib/ruby/site\_ruby/1.8/rubygems.rb:196:in `activate': can't activate rai ls (= 1.2.2), already activated rails-1.2.1] (Gem::Exception) from d:/ruby/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb: 32:in `re

This is my first go a TDD, any help would be appreciated.
