For rails-2 you need to use rspec-rails-1.3.1 (rspec-rails-2.x supports only rails ~> 3.0).

The backtrace suggests that you're actually using rspec-1 as a plugin. I'd strongly recommend that you remove the plugin and configure your app to use use rspec-rails-1.3.3 and rspec-1.3.1 gems instead. One reason is there is no easy way to tell which version of the rspec plugin you have installed.

Cheers,
David
