Hi Sylvestre,

I'm not sure of the reason, I have built in a clean chroot. This might
be caused by something in the build environment.

Basically this means that the bindings were not built. You should check
(in order):
- that you are using the configure version, not the cmake one
- that you ocaml packages are up to date (especially ocaml-ctypes, we
  might want to add a versioned build dependency)
- that the patch was applied, especially the debian/rules part (which
  removes the --disable-bindings and adds --with-ocaml-libdir=...)
- that ocaml and libs were correctly detected (this is written at the
  beginning of config.log)

Hope that helps.

Cheers,
Pierre
