This has come up before, so I know some people here have a bit of
experience with doing it.  Essentially it's possible.  I think the steps
required are:

- download a portage snapshot as you would in an initial install, or
create your own from another gentoo machine (more info here:
http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=1&chap=5#installing_portage)
- you may need to run `emerge --metadata` after unpacking it, or
something like that - someone else can comment here :)
- then follow your manual download instructions: `emerge -ufpDN world`
and download all these packages on another box
- transfer the packages to /usr/portage/distfiles, and check you got
them all with `emerge -ufDN world`.  You should have no fetch errors.
- then go! `emerge -uvaDN world`

Notes:
- when creating your own snapshot,
exclude /usr/portage/distfiles, /usr/portage/packages, (and others?)
- I would recommend -N as you might see some new features since you
haven't updated in a while

Hopefully someone will fix any holes I left, otherwise this should work!

There's a lot to be said for not saying a lot.
