Ocamlfind doesn't find arbitrary library

Ocamlfind doesn't find arbitrary library

[Garek Dyszel]

Hi Guix,

While trying to get Coq to find a certain package that is part of its
dependency chain, I stumbled upon the following seemingly-general
problem. It seems that Ocaml packages are not in general detected by
findlib.

Probably I'm missing something really simple because I'm not too
familiar with Ocaml, but it looks to me to be maybe a Guix-specific
problem.

Thanks for any and all help!
Garek

You have to add ocaml@4, otherwise Guix will not create the necessary
environment variables in the shell. With it, sha is listed.
