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

$  opam init

Run the following to initialize your environment variables:

$  eval `opam config env`

To export the needed variables every time, add them to your dotfiles.
  * On Bash, add them to `~/.bash_profile`.
  * On Zsh, add them to `~/.zprofile` or `~/.zshrc` instead.

Documentation and tutorials are available at https://opam.ocaml.org, or
via "man opam" and "opam --help".
