When trying to build hunpos,

http://code.google.com/p/hunpos/

-- under 3.11, it complains that ocamlbuildlib.cmxa cannot be found in  
`ocamlbuild -where`, and it's not there after I did make world.opt in  
the top dir of ocaml 3.11.  Going into ocamlbuild and saying make  
native leaves an boot/ocamlbuild, but end up with an error trying to  
use _build which isn't there.

Since hunpos builds fine under 3.10.2, I wonder whether this is an  
intended change in 3.11...

Cheers,
Alexy
