Note that dhcp-4.0.0-22.fc9 srpm has:
-------------------------------------------------------------
CFLAGS="%{optflags} -fPIC -D_GNU_SOURCE" \
%configure \
    --disable-dhcpv6 \
    --with-srv-lease-file=%{_localstatedir}/lib/dhcpd/dhcpd.leases \
    --with-cli-lease-file=%{_localstatedir}/lib/dhclient/dhclient.leases \
    --with-srv-pid-file=%{_localstatedir}/run/dhcpd.pid \
    --with-cli-pid-file=%{_localstatedir}/run/dhclient.pid \
    --with-relay-pid-file=%{_localstatedir}/run/dhcrelay.pid
-------------------------------------------------------------
