I've started my porting to gtk2 and I still am puzzled by some linking 
problems on my Debian box. 

I've set LD_LIBRARY_PATH and LD_RUN_PATH by hand. I can run the lablgtk2 
examples.

I've installed a basic META
======================================
requires=""
version="1.3.1"
archive(byte)="lablgtk.cma lablgnomecanvas.cma lablglade.cma gtkInit.cmo"
archive(native)="lablgtk.cmxa lablgnomecanvas.cmxa lablglade.cmxa gtkInit.cmx"
linkopts=""
directory="+lablgtk2"
======================================
with the command 
	[lablgtk-2.2.0/src/] $ ocamlfind install lablgtk2 META lablgtk.cma 
lablgnomecanvas.cma lablglade.cma gtkInit.cmo lablgtk.cmxa 
lablgnomecanvas.cmxa lablglade.cmxa gtkInit.cmx

as usual.


However, my porting candidate still shows puzzled:

Compiling a .mli file with the line
val gtkPixmap_of_file : string -> GMisc.pixmap
fails:

	$ ocamlfind ocamlopt -thread -package "pxp lablgtk2 threads pcre unix camlp4 
shell" -predicates "init threads" -c my_gtk_genericmodule.mli
File "my_gtk_genericmodule.mli", line 1, characters 34-46:
Unbound type constructor GMisc.pixmap
make: *** [my_gtk_genericmodule.cmi] Error 2

I've read the README of lablgtk2 but I can't figure out what is going on. 

How is it possible that my linking sins :-) fool ocamlfind itself?
