In /etc there will be a file called dhclient.conf. If it doesn't exist,
create it and add the following:

interface "rl0" {
prepend domain-name-servers 207.172.3.8;
prepend domain-name-servers 207.172.3.9;
request subnet-mask, broadcast-address, routers, domain-name-servers ;
require subnet-mask, broadcast-address, routers ;
}

What this will do is take the information that is provided during the dhcp
initialization and add the above to the information it recieves from the
server. If you don't want to use any of the name servers provided by dhcpd,
remote the domain-name-servers portion from the request entry. If you need
any further specifics, check out man dhclient.conf for other options to add
to this file.  I think that this will do what you're looking for though.
