Unable to build rebar3 (Ticket #62962)

[Ralph Seichter via macports-users]

My attempt to build rebar3 @3.12.0 fell flat today, and I found the Trac
ticket https://trac.macports.org/ticket/62962 . There have not been any
updates to this ticket for a year, and I wonder if the rebar3 port is
actively maintained?
