[ocaml-platform] Centos 6 OPAM Make Madness

[Louis Gesbert]

Yes, the option on `opam install` is still there. It differs in that it won't list depexts of already installed packages (it resolves the installation first, then extracts depexts).

The `--external` option on `opam list` also accepts the same tag arguments, but will list everything by tags if none are given:

$ opam install -e ubuntu google-drive-ocamlfuse
libcurl4-gnutls-dev libfuse-dev libsqlite3-dev

$ opam list -e ubuntu google-drive-ocamlfuse   
# Known external dependencies for google-drive-ocamlfuse.0.5.3 on ubuntu
libcurl4-gnutls-dev

$ opam list -e ubuntu --required-by google-drive-ocamlfuse --rec
# Known external dependencies for biniou.1.0.9, camlidl.1.05, camlp4.4.01.0, cppo.0.9.4, cryptokit.1.9, cryptokit-sha512.1.6.3, easy-format.1.0.2, extlib.1.6.1, extlib-compat.1.6.1, gapi-ocaml.0.2.1, google-drive-ocamlfuse.0.5.3, ocamlfind.1.5.1, ocamlfuse.2.7.1-cvs2, ocamlnet.3.7.4, ocurl.0.7.1, sqlite3-ocaml.2.0.6, xmlm.1.2.0 and yojson.1.1.8 on ubuntu
libcurl4-gnutls-dev
libfuse-dev
libsqlite3-dev
zlib1g-dev
