}         man 8 dhclient-script

That's doing it the hard way.  

Put something similar to the following in /etc/dhclient.conf (adjust the 
interface name to whatever is appropriate for your system):

       interface "dc0" {
           prepend domain-name-servers 127.0.0.1;
       }

You can prepend some stuff to the domain name search order (and lots of
other stuff, if you need to); see the man page for dhclient.conf for 
details.
