Hit  head.  Say oh, of course, I should have know that.

Then try it out.

hendrik@notlookedfor:~/dv/fun/wander$ make wander
ocamlfind ocamlopt -package glMLite -package unix -linkpkg wander.ml -o 
wander

File "wander.ml", line 652, characters 6-25:
Error: Unbound module Png_loader
make: *** [wander] Error 2
hendrik@notlookedfor:~/dv/fun/wander$ 

Success as far as finding the library.  But package glMLite seems no 
longer to  contain png_loader (which was there when I compiled from 
source last year).  I guess png_loader is now elsewhere?

-- hendrik
