 When I tried to install digiKam 1.2 via a fresh MacPorts setup a few days
 ago I stumbled upon the broken gtk1 port (see #24915). DigiKam depends
 upon kipi-plugins, which depends upon gdk-pixbuf, which depends upon gtk1.

 According to the gtk1 bug description the brake occurred because of the
 gettext update to version 0.18, but when I tried to downgrade gettext to
 version 0.17 many other Ports needed to be rebuilt as well, and it did not
 work.

 The kipi-plugins README says libgdk (for gdk-pixbuf) is just optional, so
 I think turning the gdk-pixbuf dependency into an optional port variant,
 as Jan did with the kdeedu4 dependency to fix #24090 would be a good
 strategy.
