title: dpkg-checkbuilddeps: Unmet build dependencies
body: <p>I am trying to build my debian package using dpkg-buildpackage in automatic manner. This is my workflow:</p>
  
  <pre><code>dpkg-buildpackage || (yes | mk-build-deps -i &amp;&amp; dpkg-buildpackage)
  </code></pre>
  
  <p>This unfortunatelly gives me </p>
  
  <blockquote>
    <p>dpkg-checkbuilddeps: Unmet build dependencies: python-virtualenv
    python-dev libssl-dev python-m2crypto virtualenv libffi-dev</p>
  </blockquote>
  
  <p>I know, I can run add <code>apt-get install</code> and those packages to my script, but once I change build deps, I have to change the script. Is there any way how to do this automatically? </p>
