<><> Handling external dependencies <><><><><><><><><><><><><><><><><><><><><><>

opam believes some required external dependencies are missing. opam can:
> 1. Run apt-get to install them (may need root/sudo access)
  2. Display the recommended apt-get command and wait while you run it manually (e.g. in another terminal)
  3. Continue anyway, and, upon success, permanently register that this external dependency is present, but not detectable
  4. Abort the installation

=> The development version of opam has been successfully compiled into /home/opam/.opam/4.14/lib/opam-devel. You should not run it from there, please install the binaries to your PATH, e.g. with
       sudo cp /home/opam/.opam/4.14/lib/opam-devel/opam /usr/local/bin

   If you just want to give it a try without altering your current installation, you could use instead:
       alias opam2="OPAMROOT=~/.opam2 /home/opam/.opam/4.14/lib/opam-devel/opam"
