The bootstrap file is an erlang script:
#!/usr/bin/env escript

When trying to reproduce this bug, I see it prints "No beam files
found". As this message is printed quite early in this script, I guess
the problem is in loading escript from the host. Unfortunately, I
wasn't able to reproduce this bug on my machine, so this is only a
guess.
Is it possible to execute ./bootstrap --help from this machine? If the
problem is in loading escript, it should lead to the same timeout
error.

By the way, it looks like rebar build tool is moving to rebar3. I'm
afraid we may have to support both until all erlang projects have
moved to rebar3 :-(
