title: Trying to install survey Gem
body: <p>I am following these guides:-</p>
  
  <p><a href="http://www.runtime-revolution.com/runtime/blog/introducing-survey" rel="nofollow">http://www.runtime-revolution.com/runtime/blog/introducing-survey</a></p>
  
  <p>When I try:-</p>
  
  <pre><code>gem "survey", "~&gt; 0.1"
  </code></pre>
  
  <p>as it suggests I get:-</p>
  
  <pre><code>ERROR: While executing gem ... &lt;RuntimeError&gt;
      Unknown command survey,
  </code></pre>
  
  <p>When I try:-</p>
  
  <pre><code>gem install survey
  </code></pre>
  
  <p>It says that everything has installed fine but when I try:-</p>
  
  <pre><code>Rails generate survey plain namespace:contests
  </code></pre>
  
  <p>or</p>
  
  <pre><code>rails generate survey:install
  </code></pre>
  
  <p>I get :-</p>
  
  <pre><code>Could not find generator
  </code></pre>
  
  <p>Also, looking in my Gemfile survey is not in there?</p>
