title: Heroku CLI not working
body: <p>Back in my office I installed heroku CLI without trouble (Ubuntu 11.04). Now, after installing it in my laptop (Ubuntu 10.04) I'm getting the following error:</p>
  
  <pre><code>$ heroku 
  /usr/local/heroku/lib/heroku/command/run.rb:1:in `require': no such file to load -- readline (LoadError)
      from /usr/local/heroku/lib/heroku/command/run.rb:1
      from /usr/local/heroku/lib/heroku/command.rb:14:in `require'
      from /usr/local/heroku/lib/heroku/command.rb:14:in `load'
      from /usr/local/heroku/lib/heroku/command.rb:13:in `each'
      from /usr/local/heroku/lib/heroku/command.rb:13:in `load'
      from /usr/local/heroku/lib/heroku/cli.rb:8:in `start'
      from /usr/bin/heroku:28
  </code></pre>
  
  <p>In both cases I followed the same procedure:</p>
  
  <ul>
  <li>Install <a href="http://toolbelt.herokuapp.com/linux/readme" rel="nofollow">heroku-toolbelt</a></li>
  <li>Install ruby with <code>sudo apt-get install ruby</code></li>
  <li>Install git</li>
  <li>Test heroku CLI: <code>$ heroku</code></li>
  </ul>
  
  <p>Can anybody help me with this?</p>
