I am using RabbitMQ with Grails, and a problem cropped up this morning. When I run rabbitmqctl status it tells me:

C:\\Users\\BuildnTest2>rab

If you run the MacPorts version of rabbitmq-server on OSX, you need to check the ~rabbitmq/.erlang.cookie file. It must match the one in /opt/local/var/lib/rabbitmq/.erlang.cookie, otherwise "rabbitmqctl" is not able to connect.
