If you're using a Postgres database (recommended):

Other optional packages :

For the google-appengine extension to be available, you also need:

* vobject - http://vobject.skyhouseconsulting.com/ -

  benefiting from a packaging system, note that vobject itself depends on

Any help with the packaging of CubicWeb for more than Debian/Ubuntu (including
eggs, buildouts, etc) will be greatly appreciated.
