building the revivesa branch

[Eric Haszlakiewicz <erh%nimenees.com@localhost>]

I just tried building the revivesa branch by
cd /usr/src
cvs up -dP -rwrstuden-revivesa

but that ran into problems with missing directories (src/external and 
src/sbin/dhcpd so far).  What's the right way to update to get a working 
revivesa source tree?  Should I only update src/sys and src/lib?  Or 
should I just wait until it gets merged?
