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](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
