title: Install python-scipy in a virtualenv
body: <p>I'm trying making work scipy in my virtualenv but the only way to install it is with apt-get and there is not a way to install it for my virtual env. Doesn't exits a package for pil, so i tried copy the folder
  <code>/usr/lib/python2.7/dist-packages/scipy</code> to <code>/home/envs/conbert/lib/python2.7/site-packages</code> but is not working. Is possible make work scipy for a specific environment?</p>
