Actually, I suspect the problem is that you don't have PMI running on the machine. The processes have no reason to be opening sockets for the OOB on a Cray XE6, and if you look at that platform file, it defines the location of the PMI libraries that are required.
Since it built, I expect the libraries were found. However, you should check to ensure your sys admin actually has PMI running.
