dhclient doesn't know that you want to use a local cache, so it does
what it does - gets resolver addresses from your ISP.

Put this in your /etc/dhclient.conf:

interface "hme0" {    <---  Change interface name accordingly...
    supersede domain-name-servers 127.0.0.1;
}


And try again.  I believe, but haven't tested it, that you can use
prepend instead of supersede is you wish to keep your ISP's resolvers in
case your cache fails - but don't quote me on that!  ;-)

As for search order, use prepend:

interface "hme0" {
    prepend domain-name "your.domain.here";
}
