I run v1to2.sh, included in this gist, to get everything in place in /tmp/beat

> sh v1to2.sh 
Switched to branch 'v1'
==> beat_core (clean)
==> beat_tcp_api (clean)
==> beat (clean)
... 99 skip a few ...
a ./erts-5.9.3/bin/typer
a ./bin/beat
a ./bin/beat-0.1.0
a ./bin/beat-0.1.1
a ./bin/install_upgrade.escript
a ./bin/start_clean.boot

Confirming everything looks pretty decent and starting up a background node:

> cd /tmp/beat 

> ls bin 
beat                    install_upgrade.escript
beat-0.1.0              start_clean.boot

> ls releases 
beat-0.1.0        beat-0.1.1.tar.gz

> ./bin/beat-0.1.0 start

> ./bin/beat-0.1.0 attach
Attaching to /tmp//tmp/beat/releases/beat-0.1.0/erlang.pipe.1 (^D to exit)

Anyone see what I'm doing goofy?
