title: How to fix libv8 error from Gemfile on Mavericks?
body: <p>When I run <code>bundle install</code> I get</p>
  
  <pre><code>An error occurred while installing libv8 (3.11.8.17), and Bundler cannot continue.
  Make sure that `gem install libv8 -v '3.11.8.17'` succeeds before bundling.
  </code></pre>
  
  <p>Libv8 is dependency for <code>lunchy</code> and <code>therubyracer</code> gems.</p>
  
  <p>I have locked in my <code>Gemfile.lock</code> libv8 gem on <code>3.11.8.17</code></p>
  
  <p>But I found that I can downgrade it to <code>3.3.10.4</code></p>
  
  <p><a href="https://stackoverflow.com/questions/8126465/bundle-install-update-libv8-therubyracer-installation-fails-with-native-ex">bundle install / update: libv8 (therubyracer) installation fails (with native extensions)</a></p>
  
  <p>How to do that?</p>
  
  <p>I also found working <code>3.11.8.17</code> gem but don't know how to implement it on my system.
