Or you could just `make packages` on your fast builder machine and then
use pkg(8) to install on your slow machines.

Either NFS mount the repository directory, or stand up a fairly simple
webserver to provide the packages over your network.

This also will allow you to prune out a lot of debug symbols and other
bits and pieces you probably won't want eating up space on something
like an RPi
