    >> Is another interactive backend supported for matplotlib?

    Jochen> I am happily using GTKagg with MacPort's python25 on Leopard.

I tried that but get this traceback:

    % /opt/local/bin/python2.5

    ImportError: No module named _backend_gdk

Given that py25-matplotlib didn't depend on py25-gtk, my guess is that it
wasn't built with Gtk support.  How do I do that?

Thx,
