That usually means you generated your apps using rails 2.1 (or edge
rails) but the app itself is running 2.0.2.
This happened to a lot of people that had used aptana at least once
because it added stuff to your gem sources list.
Removing the offending line from your environment.rb should do the
trick, and you should probably check the versions of the rails gems
you have installed.
