Added ./rel/relx.config as per your 'recipe' - and 'fire in the hole' ;)

$ MIX_ENV=prod mix release
==> Assembling release..
==> Building release bird:0.0.1 using environment prod
==> Including ERTS 8.3 from /usr/local/Cellar/erlang/19.3/lib/erlang/erts-8.3
==> Packaging release..
==> Release successfully built!
    You can run it in one of the following ways:
      Interactive: _build/prod/rel/bird/bin/bird console
      Foreground: _build/prod/rel/bird/bin/bird foreground
      Daemon: _build/prod/rel/bird/bin/bird start

Which to me seemed not to cut the mustard, then instead, I tried to change rel/config.exs from:

environment :prod do
  set include_erts: true
  set include_src: false
  set cookie: :"A:t(qxF@6:o;LWGqm^E7=|>Jx9I^$Mu({`:dL*@PTTMh8:xLTff^Zdsz.X765]Po"

to:

environment :prod do
  set include_erts: false
  set include_src: false
  set cookie: :"A:t(qxF@6:o;LWGqm^E7=|>Jx9I^$Mu({`:dL*@PTTMh8:xLTff^Zdsz.X765]Po"

which gave me this:

$ MIX_ENV=prod mix release

IMPORTANT: You have opted to *not* include the Erlang runtime system (ERTS).
You must ensure that the version of Erlang this release is built with matches
the version the release will be run with once deployed. It will fail to run otherwise.
