why? My original interest in actually finding out why is somewhat

"man port" is quite informative.  "port rdeps portname" gives you the
dependency tree (doesn't really understand general graphs, it assumes
simple DAGs) for "portname"; it won't produce e.g. "dot" input for you,
though.

In this case, the dependency appears to be

gimp
  icns-gimp
    gimp2
      libgnomeui
        libgnome-keyring
          gnome-keyring

(which makes me think gimp is a metaport, so start at gimp2...)
