----------------------+--------------------
 gajim version 0.16.1 was released 28 February 2015.

 Current port fails because of its dependency on dbus-python26. dbus-
 python26 was been replaced by dbus-python27 and no longer exists.
 Upgrading to python27 is, therefore, required, at a minimum, to get it
 working again.
