> I suppose there isn't a "right way" since MacPorts is not designed to be used like that. What you describe should work, but it would only be a one-time copy from machine A to B (C, D, etc.). If you later install additional software on A, you'd then have to install it separately on B (C, D, etc.). Unless you look into using rsync or something to sync them up.

It's roughly the same effort to copy a fresh installation than it is to run the installer on each machine, so why not do it the expected way?

You could setup a www server on one of the machines to offer up software available in
/opt/local/var/macports/software, which is where the binary archives live.

You then add that machine to

Note that you'll need to setup a signing key for the packages. Some helpful instructions are available on the MacPorts site:
