<><> 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

=> afl-persistent is installed, but since the current OCaml compiler does
   not enable AFL instrumentation by default, most packages will not be
   instrumented and fuzzing with afl-fuzz may not be effective.

   To globally enable AFL instrumentation, create an OCaml switch like:

     opam switch create 5.4.0+afl ocaml-variants.5.4.0+options ocaml-option-afl
