title: Apt-Get not finding Packages
body: <p>I`m currently trying to install the mysql packages for a rails 3 app via apt-get, so I can get the corresponding gems working.</p>
  
  <p>When I run :</p>
  
  <pre><code>sudo apt-get install libmysql-ruby libmysqlclient-dev
  </code></pre>
  
  <p>I get:</p>
  
  <pre><code>E: Couldn't find package libmysql-ruby
  </code></pre>
  
  <p>I when try to update apt, I get:</p>
  
  <pre><code>Reading Package Lists... Done
  Building Dependency Tree... Done
  </code></pre>
  
  <p>If this helps, apt got install via Fink for max osx (10.7)
  I would appriciate anykind of help with this issue.</p>
