[macports] Building in a jail?

[James Sumners]

I just upgraded from a PowerBook to a MacBook Pro. The migration
assistant tool kept my old macports system intact. I can still run all
of the ports I had installed; particularly, I can still use TeXmacs
and teTeX. However, I had built all of my ports as PPC binaries, so
they are running via Rosetta. This also means I can't update any of my
ports because port fails to recognize the architecture. Since there
have been so many posts lately about things failing to build on 10.5,
I'm a little scared to wipe my old macports system and rebuild from
scratch. I particularly can't afford to be without a LaTeX environment
right now.

So, is there any way I can "jail" a new installation of macports? If I
can build everything successfully, I want to be able to delete the old
version and move the new one to the standard location.
