The rails-3.0.1 release excluded a change that I had naively expected to be included. This upgrade is only necessary if you write view specs and are upgrading to rails-3.0.1. To upgrade, all you need to do is change your Gemfile to read:

gem "rspec-rails", "2.0.1"

And then run

bundle update rspec-rails
