title: installing PyGObject via pip in virtualenv
body: <p>I'm actually upgrading an old django app from python2.7 to python3.4. While installing pygobject via pip, I got this error:</p>
  
  <pre><code>Collecting pygobject
    Using cached pygobject-2.28.3.tar.bz2
      Complete output from command python setup.py egg_info:
      Traceback (most recent call last):
        File "&lt;string&gt;", line 20, in &lt;module&gt;
        File "/tmp/pip-build-9dp0wn96/pygobject/setup.py", line 272
          raise SystemExit, 'ERROR: Nothing to do, gio could not be found and is essential.'
                      ^
      SyntaxError: invalid syntax
  
      ----------------------------------------
  Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-9dp0wn96/pygobject
  </code></pre>
  
  <p>I am trying to install it in a virtualenv. System-wide installation doesn't work either... I am working on arch linux with python3.4</p>
  
  <p>I have installed the arch package named pygobject-devel 3.16.2-1 but I still can't import gobject python module</p>
  
  <p>What is this damned missing gio?</p>
  
  <p>Any help is welcomed...
  Thanx in advance !</p>
