FWIW it builds and starts up fine on FreeBSD with
mDNSResponder-878.1.1 installed (Apache-licensed Apple Bonjour code)
and the mdnsd daemon started. If I don't start mdnsd it shows an
error at startup. When built against the (conflicting)
avahi-libdns-0.6.31_2 package it shows the WARNING you reported and
"DNSServiceRegister() failed: error code -65537", which might just
mean it wants to talk to some daemon I'm not running.
