Comment (by mascguy):

 Four of these libs are now updated, as of this writing: `atkmm`, `glibmm`,
 `cairomm`, and `pangomm`. In addition, new ports have also been created,
 to provide legacy bindings: `atkmm-1.6`, `glibmm-2.4`, `cairomm-1.0`, and
 `pangomm-1.4`. (The latter ports provide drop-in API/ABI compatibility, to
 avoid breaking any existing binaries.)

 The remaining ones, such as `gtkmm3` et. al., are next on the list. Those
 will be tackled soon, as time allows.
