Please send us the modified code.

There must be a step 0) missing here. amqp_bind does not create any 
queues and will fail if the referenced queues do not exist. So how are 
the queues created? Please send us the code/scripts for that.

Also, are all the above running on the same machine as the broker?

ok. That's useful to know.

Btw, what revision of the server are you running? 'hg id' will tell you.
