The rabbitmq code is installed in /usr/lib/erlang/lib/rabbitmq_server... 
But, when trying to start the server via

I get:

And the log shows:

The /etc/init.d/rabbitmq-server script starts /usr/sbin/rabbitmq-multi, 
which in turn does:

It is looking in /usr/sbin/../ebin for erlang code. It isn't in that 
path when starting the server this way. Unless I put a symlink in 
/usr/lib/erlang/lib/rabbitmq_server-1.4.0/bin it doesn't find the .beam 
files.

I am using apt-get to install the rabbitmq server pkg. Is there 
something else I should be doing?

Using the instructions here:
