No subnet declaration for eth0 (no IPv4 addresses).

I'm running dhcpd on Slackware 15.0. I get the following message in syslog:
Code:Feb 16 19:24:59 mail dhcpd: No subnet declaration for eth0 (no IPv4 addresses).
Feb 16 19:24:59 mail dhcpd: ** Ignoring requests on eth0. If this is not what
Feb 16 19:24:59 mail dhcpd: you want, please write a subnet declaration
Feb 16 19:24:59 mail dhcpd: in your dhcpd.conf file for the network segment
Feb 16 19:24:59 mail dhcpd: to which interface eth0 is attached. **
Feb 16 19:24:59 mail dhcpd:
Feb 16 19:24:59 mail dhcpd: Not configured to listen on any interfaces!My subnet declaration in /etc/dhcpd.conf is:
Code:authoritative;

zone hprs.local. { primary 192.168.0.2; }
zone 0.168.192.in-addr.arpa. { primary 192.168.0.2; }

subnet 192.168.0.0 netmask 255.255.255.0 {
option routers 192.168.0.1;
range 192.168.0.100 192.168.0.254;
option domain-name-servers 192.168.0.2;
option domain-name "hprs.local";
ddns-domainname = "hprs.local.";
ddns-rev-domainname = "in-addr.arpa.";
}dhcpd works fine on this network, so what is this error about?

I've found plenty of Internet postings on this but no actual explanation.
