Acts as ferret : only have one instance per development computer...

Symptoms

I kept getting this stupid error
(druby://localhost:9010) /Users/nerb/.gem/ruby/1.8/gems/activesupport-2.1.2/lib/active_support/dependencies.rb:279:in `load_missing_constant': uninitialized constant Browser (NameError)


How to solve this error

Basically I got this error because Acts as ferret was running in another app on my development box. Just do a simple script/ferret_server stop in the OLD app. Return to the new app and start the ferret server by doing script/ferret_server start

Hell, i thought it had to do with my recent updating of rails to 2.2.2, however, it did not.
