opam-depext doesn't recognise libgmp-dev or libssl-dev #139

I am trying to install the dependencies for ocaml.org but run into the following error when running opam depext ocamlorg:

# Detecting depexts using vars: arch=x86_64, os=linux, os-distribution=linuxmint, os-family=ubuntu
# The following system packages are needed:
libgmp-dev
libssl-dev
Sorry, don't know how to install packages on your ubuntu system

I have followed the 'up and running' steps on ocaml.org and intsalled libgmp-dev and libssl-dev

This works with opam 2.1, if you're happy to install a pre-release (you just run opam install conf-gmp conf-libssl in 2.1 - there's no need to run the depext command separately).

Alternatively, you can persuade opam-depext to work by adding OPAMVAR_os_family=debian to the call: i.e. OPAMVAR_os_family=debian opam depext -i conf-gmp conf-libssl.

Thanks I'll give that a shot.

I'm sure Linux Mint used to work with the opam 2.0 depext though; perhaps something has changed in the /etc/os-release variables upstream.

They changed in Mint 18 (2016), it would appear: https://bugs.launchpad.net/linuxmint/+bug/1641491
