title: Error / warning messages on git push
body: <p>When I perform a successful <code>git push</code>, I receive the following messages.</p>
  <blockquote>
  <p>remote: /usr/bin/env: ruby: Arquivo ou diretório não encontrado</p>
  <p>error: cannot run hooks/post-receive: No such file or directory</p>
  </blockquote>
  <p>Why is it looking for ruby and why is it trying to perform some post-receive hook?</p>
