The best solution is to install the sysutils/screen port and run your
build process in a window under that.  Then you can attach to that
screen session from any number of other logins (at the same time even). 
As a side-effect, screen will protect you from accidental terminal
disconnections (if you close your xterm or ssh disconnects on you,
screen will detach the session and it will run headless until you
reattach to it).

The next-best is to use the /usr/sbin/watch command to attach to an
existing tty and see its screen output.  You'll need to rebuild your
kenel and add the "snp" device (or load it as a module).
