 After syncing and upgrading my ports yesterday, libpng was bumped from 1.2
 to 1.4, and so the shared library was renamed from libpng12 to libpng14. A
 whole bunch of ports then stopped working because they linked against the
 old library and didn't receive a version bump to link against the new
 library they depended on. Here is a (perhaps incomplete) list:

  * evince
  * gnome-desktop
  * libbonoboui
  * libcanberra
  * libgnomecanvas
  * libgnomeui
  * libgsf
  * libnotify
  * libunique
  * nautilus
  * vte

 I already reported the problem with vte (#28016, which is how I first
 noticed something was wrong), but the other ports are still unreported.
