title: i18n-js on Rails 2.3.5 installation
body: <p>I feel like a moron because this gem seems to be a widely used, but I can't set it up.</p>
  
  <p>I'm on the <a href="https://github.com/fnando/i18n-js" rel="nofollow">i18n-js github page</a> and I'm following the instructions:</p>
  
  <pre><code>gem install i18n-js
  rake i18n:js:setup # Rails &lt;= 3.0
  </code></pre>
  
  <p>And, though the gem is is now installed, I get:</p>
  
  <blockquote>
    <p>Don't know how to  build task 'i18n:js:setup'</p>
  </blockquote>
  
  <p>Which it's actually no big surprise because I don't think it's enough to have the gem in your gemlist to add some task, right?</p>
  
  <p>I also tried adding this line below, but, though the gem it's now shown as a dependency and I can access <code>SimplesIdeias::I18n</code>, the rake task is still not available.</p>
  
  <pre><code># environment.rb
  config.gem 'i18n-js'
  </code></pre>
  
  <p>What am I doing wrong?</p>
  
  <p>Thanks</p>
