Basically.. I am breaking things down from another article which I used to set up virtual domains and accounts that accept incoming email..
1. First off get a fresh version of freebsd (using 8.2-STABLE).
#cvsup -h server.freebsd.org /usr/share/examples/cvsup/stable-supfile
This will make sure your freebsd kernel and libs is up to date. This also caches the updates for existing software that will been to be installed.
2. Let yourself not stress out for 5-7 mintes! Scoot!!
