Rails_security Restful Authentication

Hi, I'm running into problems when trying to get restful_authentication with the --aasm option working. I am a Rails newbie. I performed the following steps from the the instructions at http://github.com/technoweenie/r... to create a sample site using restful authentication with AASM.

1. Installed the restful_authentication plugin: git clone git://github.com/technoweenie/restful-authentication.git restful_authentication

2. Installed the rubyist-aasm gem following the instructions provided there, i.e. sudo gem install rubyist-aasm
   I believe the aasm gem was installed correctly, because I can load it from irb or script/console. I was also able to execute the test steps outlined here by Scott Barron with this result:

   irb(main):001:0> require 'rubygems'
   => true
   irb(main):002:0> require 'aasm'
   => true
   irb(main):003:0> class Conversation
   irb(main):004:1> include AASM
   irb(main):005:1> aasm_initial_state :new
   irb(main):006:1> aasm_state :new
   irb(main):007:1> aasm_state :read
   irb(main):008:1> aasm_event :view do
   irb(main):009:2* transitions :to => :read, :from => [:new]
   irb(main):010:2> end
   irb(main):011:1> end
   => #Proc:0xb7b3fd14@/usr/local/lib/ruby/gems/1.8/gems/rubyist-aasm-2.0.2/lib/aasm.rb:59
   irb(main):012:0> Conversation.new.view!
   => true
   irb(main):013:>
   

3. Generated the restful auth code: ./script/generate authenticated user sessions --aasm

4. Updated routes.rb and environment.rb as directed

5. The following error stack was produced when I ran ./script/server (sorry it's so long). If I commented out the user_observer statement in environment.rb, the application started up OK, but died in User#new with the same error "uninitialized constant Authorization::AasmRoles::AASM":

=> Booting Mongrel (use 'script/server webrick' to force WEBrick)
=> Rails 2.1.0 application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
** Starting Mongrel listening at 0.0.0.0:3000
