When I installed only pygobject3 I got the following error when running a python script:

    gi.require_version('Gtk', '3.0')
  File "/usr/local/lib/python2.7/site-packages/gi/__init__.py", line 102, in require_version
    raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace Gtk not available

So it seems to me that you need to install both packages to get gtk3 with python bindings on Mac OS X:

brew install gtk+3 pygobject3
