title: Couldn't find 'devise_install' generator - Rails 2.3.8, Devise 1.0.8
body: <p>I'm trying to get Devise up and running with a freshly generated Rails 
  2.3.8 app.</p>
  
  <p>This is the error I'm running into:</p>
  
  <pre><code>devise &gt; script/generate devise_install
  Couldn't find 'devise_install' generator
  </code></pre>
  
  <p>I do have the Devise and Warden gems specified in my config file:</p>
  
  <pre><code>config.gem 'warden', :version =&gt; '0.10.7'
  config.gem 'devise', :version =&gt; '1.0.8'
  </code></pre>
  
  <p>The gems are installed:</p>
  
  <pre><code>devise &gt; rake gems 
   - [I] warden = 0.10.7
      - [R] rack &gt;= 1.0.0
   - [I] devise = 1.0.8
      - [I] warden ~&gt; 0.10.3
         - [R] rack &gt;= 1.0.0
  I = Installed
  F = Frozen
  R = Framework (loaded before rails starts)
  </code></pre>
  
  <p>Looking at the list of generators, I don't see anything from Devise:</p>
  
  <pre><code>devise &gt; script/generate
  Installed Generators
    Rubygems: cucumber, facebook, facebook_controller,
  facebook_publisher, facebook_scaffold, feature, integration_spec,
  publisher, rspec, rspec_controller, rspec_model, rspec_scaffold,
  session, xd_receiver
    Builtin: controller, helper, integration_test, mailer, metal,
  migration, model, observer, performance_test, plugin, resource,
  scaffold, session_migration
  </code></pre>
  
  <p>Any clues?</p>
