Should only compile gettext messages when building sdist

  Running setup.py install for django-autocomplete-light
      sh: 1: django-admin.py: not found

You cannot have django-autocomplete-light with `pip install -r requirements.txt` when django itself is part of that file -- in that case `django-admin.py` won't be in the executable path.
