Updating libpng from @1.2.44_0 to @1.4.5_0 leaves libcanberra, libgsf, libnotify linking against a non-existent library

[cubranic@…]

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.

Most of those have already been rev bumped.

Confirming that libcanberra, libgsf, and libnotify are the only remaining ports on my machine that link against libpng12.

Replying to cubranic@…:

Confirming that libcanberra, libgsf, and libnotify are the only remaining ports on my machine that link against libpng12.

Anjuta, geany, gedit, mousepad, gwget, qalculate-gtk, glade also link against libpng12 and don't check for any other.

Libnotify was done in r75241.
