There were changes in R14B relating to epmd name registration messages
from localhost which may be relevant to this error.

Can you try the same test, but with epmd debug output?
$ epmd -kill
$ epmd -d
Then in a different shell:
$ erl -sname test
I would expect debug output similar to this in the first shell on a
epmd running - daemon = 0

If this doesn't work then you will have difficulties with any
distributed Erlang software, not only RabbitMQ.
The problem you describe may be caused by FreeBSD jails, which treats
localhost specially. Is that what you are using? If so then I'm not sure
there is a good solution other than reverting to R13B03 (or any version
of Erlang prior to R14B). There may also be patches to Erlang that work
around the problem, but a FreeBSD mailing list would be the right place
