 > I've uploaded my take on updating Portfile, but I'm not very experienced
 with Portfile writing, so someone should review it.

 I came up with nearly the same solution as you, but I don't think the
 {{{port:libpng port:zlib}}} but {{{port:gettext}}} are needed as
 depends_lib. {{{otool -L}}} only shows libglib-2.0.0.dylib and
 libintl.8.dylib.
