Hi!

I tried building your file (it's technically not a manifest) and indeed it's failing in the chack-findlib-path.

Why do you want to run it? There's no way it could work at this point, right after the check phase, since the package is not even installed yet. Also, the OCAMLPATH that would allow findlib to find it is not set to the outputs, only to the inputs.
