Thanks, RW.  I had assumed that and had hoped to run my make  
buildworld, make buildkernel, mergemaster, make installkernel and make  
installworld then upgrade all ports.

The problem is that I haven't been able to figure out, how to build  
using all amd64.

Again very dumb on my part, I'm sure.
