title: Rails 2.2.2 issue: undefined method `activate_bin_path' for Gem:Module (NoMethodError)
body: <p>I am working on Rails 2.2.2 application. For this I installed rvm with Ruby version 1.9.3p551. There  is no Gemfile for this application. So as mentioned in the environment.rb file I created a Gemfile with rails and sqlite3. While running rake db:create, I am facing the following issue.</p>
  
  <pre><code>whoami@myvm:~/Desktop/practice/store$ rake db:create
