The package failed to build. The error log from opam follows.

[NOTE] Package ocamlfind is already installed (current version is 1.9.6).
The following actions will be performed:
=== install 2 packages
  - install conf-pkg-config 4

    libavutil-dev libswscale-dev pkg-config

<><> 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
