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
