The current version of RabbitMQ is 3.6.3, so maybe this problem has been fixed upstream.

Workaround for anyone who cannot install rabbitmq-server because of this issue:

1. cd /tmp
2. svn checkout -r 147014 https://svn.macports.org/repository/macports/trunk/dports/lang/erlang
3. cd erlang
4. sudo port install
5. sudo -n port install rabbitmq-server

Notes:

• Step 2 checks out a previous revision of the Erlang Portfile which references version 18.3.
• The -n in step 5 is critically important; it tells MacPorts not to upgrade dependencies. Without this switch, MacPorts will try to install Erlang 19!

If step 4 fails because of a build error, you may be able to get it to work by building manually:

1. cd "/opt/local/var/macports/build/_private_tmp_erlang/erlang/work/erlang-18.3"
2. sudo make -w all
3. cd -
4. Retry step 4 above.
