title: Rebuild uwsgi with pcre support
body: <p>When running uwsgi I got the following message:</p>
  <pre><code>!!! no internal routing support, rebuild with pcre support !!!
  </code></pre>
  <p>I already have installed pcre (I think) with the following command:</p>
  <pre><code>sudo apt-get install libpcre3 libpcre3-dev
  </code></pre>
  <p>Why am I still getting this message even after I have installed the <code>pcre</code> package, if I need to reinstall <code>uwsgi</code> and activate <code>pcre</code>, how do I do it?</p>
  <p>Also, does internal routing matter?</p>
  <p>I assume it does or else the makers of <code>uwsgi</code> wouldn't have made the message come up. I am running <code>Ubuntu 12.04 LTS</code>.</p>
