	That would only be true if he wanted to set his named up as a forwarder.
What most people mean by "caching only" is that the local named does the
resolution and caches the responses, but it's not authoritative for any
zones. 

	On freebsd systems all you have to do is run the makerev script in
/etc/namedb and then fire up named. I usually symlink
/etc/namedb/named.conf to /etc/named.conf because I'm kind of a purist
about such things, but that's not mandatory if you use '/usr/sbin/named -c
/etc/namedb/named.conf' to start it. 

Good luck,

Doug
