how do i build / apply an selinux policy file, on redhat 7?

I'm trying to install RabbitMQ on Redhat Linux 7 (RHEL7). I followed the instructions on the RabbitMQ site, and it installed fine. However, it won't run because SELinux is preventing Erlang from binding to port 25672. I've found the SELinux policy files in the SELinux repository on github, but I don't know how to build them and apply them. My google-searching has been unsuccessful as I keep coming up with references to other linux distributions, or the use of audit2allow. How do I apply the rabbitmq policy files from https://github.com/selinux-policy/selinux-policy/tree/f21-contrib to my RHEL7 box?
