Ahhh, this explains what's going on here. Yes, I would also go for a new
port name as gdk-pixbuf still has dependents.

So we definitely need a gdk-pixbuf2 port and have multiple options to
implement this at the time gtk2 gets updated to 2.22.0:

a) gtk2 @0.22.0 adds a dependency on gdk-pixbuf2

   Complicated upgrade path, as gdk-pixbuf2 needs to replace files from
   gtk2 <0.22.0. The upgrade will not be straight forward, but could be
   done with some hack inside a pre-activate phase in gdk-pixbuf2.


b) gtk2 @0.22.0 does *not* add a dependency on gdk-pixbuf2, but
   this is added to individual ports

   Easy upgrade path, but a lot of work as this means scanning all
   recursive dependents of gtk2 for linkage with libgdk-pixbuf*.dylib.
