make produced this compilation error:

discoverer_async.c: In function ‘discovery_async_poller_dns_init’:
discoverer_async.c:39:76: error: ‘EVDNS_BASE_INITIALIZE_NAMESERVERS’ undeclared (first use in this function)
  if (NULL == (poller_config->dnsbase = evdns_base_new(poller_config->base, EVDNS_BASE_INITIALIZE_NAMESERVERS)))

My guess is the macro EVDNS_BASE_INITIALIZE_NAMESERVERS is only defined in a newer version of libevent.  My server has v2.0.21 installed and documentation states v1.4 or newer.
