I'm no scripter, but something like this would work I

Modify the pertinent files so that when you issue a
"service dhcpd start", it first puts out a dhcp
request for a bogus interface.  If it receives an IP
address, then there is already a dhcp server on the
network and your new dhcp server should not be allowed
to start.
