[erlang-questions] erlpass issue

[Fred Hebert]

If you're still on rebar2, use the prior-to-last tagged version. I 
recently bumped it to rebar3 and that broke rebar2 support 
inadvertently.

If using rebar2, you should *never* rely on the master branch because 
the tool itself does not support automatically converting that to a 
stable reference. Rebar3 would instead generate a lock file that ensures 
you keep using the proper version, though.

Let me know if that helps.

Regard,
Fred.
