just installed acts_as_state_machine and now cant launch the server

I just installed AASM and when I run 'ruby script/server' it fails with:

=> Booting Mongrel (use 'script/server webrick' to force WEBrick) => Rails 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 ** Starting Rails with development environment... Exiting C:/dev/ruby/lib/ruby/gems/1.8/gems/activesupport-1.4.4/lib/ active_support/dependencies.rb:477:in `const_missing': uninitialized constant Rails::Initializer::ScottBarron (NameError)

the plugin is installed in the vendor/plugins

I can see the code that declares the modules, so it seems like all should be cool. I must be missing something... any ideas?

Thx

never mind... I installed the plugin and in the process got the previously tagged versions... once I removed them, it all worked fine
