strange enough, lablgtk2.10.1 won't compile

Hi,

I get the following error when trying to compile lablgtk 2.10.1

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
make[1]: *** [gContainer.cmo] Error 2
make: *** [world] Error 2

Ok, it's on  a Mac... I got gtk2 (2.12.9)  from Macports, then first  
configured as follows

 > configure --enable-debug CPPFLAGS=-I/opt/local/include LDFLAGS=-L/ 
opt/local/lib

which resulted in

LablGTK configuration:
         threads         system
         GtkGLArea       not found
         libglade        not found
         librsvg         not found
         libgnomecanvas  not found
         libgnomeui      not found
         libpanelapplet  not found
         gtkspell        not found
         gtksourceview   not found

         debug           yes
         C compiler      gcc

I also tried

 > configure --without-gl --without-glade --without-rsvg without- 
gnomecanvas --without-gnomeui --without-panel --without-gtkspell  
CPPFLAGS=-I/opt/local/include LDFLAGS=-L/opt/local/lib

and got the warning

configure: WARNING: you should use --build, --host, --target

and the result

LablGTK configuration:
         threads         system
         GtkGLArea       disabled
         libglade        disabled
         librsvg         disabled
         libgnomecanvas  not found
         libgnomeui      disabled
         libpanelapplet  disabled
         gtkspell        disabled
         gtksourceview   not found

         debug           no
         C compiler      gcc

In both cases the thing won't compile.

It's a bit frustrating, since I don't plan any development, it just  
would be nice to have Coqide on my mac. Any comment welcome.

Cheers,

Krzysztof
