I believe TCP works fine, Jody, as it is used on Macs fairly widely. I suspect this is something funny about your installation.
One thing I have found is that you can get this error message when you have multiple NICs installed, each with a different subnet, and the procs try to connect across different ones. Do you by chance have multiple NICs? Have you tried telling OMPI which TCP interface to use? You can do so with -mca btl_tcp_if_include eth0 (or whatever you want to use).
