Static Erlang

Hi Grzegorz,

How about flipping the script.

I'm not releasing on FreeBSD, but Debian.

What we do do is build a release of the app/project on the target version.
The release includes Erlang.

We then build a Deb which defines the dependencies for that build/release.

In short, Erlang is not a dependency since it's built and included in the
package. The dependancies used to build the release, which are standard
packages on the target platform are dependencies of my Deb.

Maybe that makes sense?

Kind regards,
