[rabbitmq-discuss] Problems with running RabbitMQ auth backend http plugin built from source with RabbitMQ 3.1.5 release

[Akbar Pirani]

I am using RabbitMQ 3.1.5 on Mac OS X 10.8.4 (12E55) installed using brew.
Since the rabbitmq-auth-backend-http plugin is not provided with the
release I built it from the source using the build process described at
http://correlia.blogspot.com/2012/07/rabbitmq-with-http-backend-plugin.html
 and http://www.rabbitmq.com/plugin-development.html

The plugin was built using Erlang R15B03 (erts-5.9.3.1). Then I copied the
built plugin in rabbitmq plugins directory and enabled it and tried to use
it by making a web stomp request. I am getting the following error
in rabbit at localhost.log

Any ideas on what the problem is and how it can be resolved?
