    OPAM uses ~/.opam by default to install packages, so you need to initialize
    the package database first by running (as a normal user):

    $  opam init

    and add the following line to ~/.profile to initialize the environment:

    $  eval `opam config -env`

    Documentation and tutorials are available at http://opam.ocamlpro.com, or
    via 'man opam' and 'opam --help'.
