title: mcrypt.ini doesn't exist in my directory
body: <p>I'm using ubuntu 13.10. I  need mcrypt extention on my terminal. My server already have installed it. I follow this <a href="https://stackoverflow.com/questions/19446679/mcrypt-not-present-after-ubuntu-upgrade-to-13-10">question</a> and <a href="https://bugs.launchpad.net/ubuntu/+source/php-mcrypt/+bug/1241286" rel="nofollow noreferrer">lunchpad</a>.<br>
  So I execute this commant:</p>
  
  <pre><code>sudo ln -s /etc/php5/conf.d/mcrypt.ini /etc/php5/mods-available
  sudo php5enmod mcrypt
  sudo service apache2 restart 
  </code></pre>
  
  <p>But when I try to above second line  <code>sudo php5enmod mcrypt</code> command, Then I see a warning:</p>
  
  <blockquote>
    <p>WARNING: Module mcrypt ini file doesn't exist under
    /etc/php5/mods-available.</p>
  </blockquote>
  
  <p>How can I solve this problem?</p>
