[ocaml-platform] Centos 6 OPAM Make Madness

[Louis Gesbert]

We are still improving on handling of dependencies towards system packages, but in OPAM 1.2 you can get an overview of the documented system dependecies of a package with:

$ opam list google-drive-ocamlfuse --external


Or to get it recursively for all (OPAM) dependencies:

$ opam list --required-by google-drive-ocamlfuse --rec --external
