FreeBSD Port: net/unison .. does not compile

[mato]

Hallo,

Port net/unison does not compile :

[...]
ocamlc.opt   -w s -c ogtkActionProps.ml
ocamlc.opt   -w s -c ogtkBrokenProps.ml
ocamlc.opt   -w s -c gContainer.mli
ocamlc.opt   -w s -c gContainer.ml
The implementation gContainer.ml does not match the interface 
gContainer.cmi:
Values do not match:
  val pack_container :
    create:(([> `container | `widget ] as 'a) Gobject.param list ->
            (#GObj.widget as 'b)) ->
    'a Gobject.param list ->
    ?border_width:int ->
    ?width:int ->
    ?height:int -> ?packing:(GObj.widget -> unit) -> ?show:bool -> unit 
-> 'b
is not included in
  val pack_container :
    create:([> Gtk.container ] Gobject.param list -> (#GObj.widget as 
'a)) ->
    [> Gtk.container ] Gobject.param list ->
    ?border_width:int ->
    ?width:int ->
    ?height:int -> ?packing:(GObj.widget -> unit) -> ?show:bool -> unit 
-> 'a

This is on 7-STABLE and at least previous version of unison worked on 
6-STABLE.
