title: graphite installation throwing error
body: <p>I have graphite 0.9.10 on ubuntu 13.  When I run the 'run-graphite-devel-server.py' script in the /opt/graphite/bin directory, the server comes up.  However, when I access the url on port 8080, I receive the following (500 internal server) error:</p>
  
  <pre><code>SuspiciousOperation: Invalid HTTP_HOST header (you may need to set ALLOWED_HOSTS)
  </code></pre>
  
  <p>Any ideas on how to troubleshoot/resolve the issue.</p>
