Actually, is there some explicit provision for building a new
/opt from scratch in some other directory, then switching
it in as "the" new /opt (macport binaries).

The thing about such a massive migration is that I'd like to minimize
working downtime. So my current /opt directory is working quite well,
but if I do the correct thing, then I've potentially got a lot of
development downtime while I'm building all the new binaries.

The only obvious thing that comes to mind is building the ports
on another machine and then copying them over and installing them
as binary packages.
