OK, my logs do have an EntryGroupNew entry - here's the whole group of 
messages:

OK, I tried 'avahi-browse  _http._tcp' and 'avahi-browse  _ftp._tcp'  but no 
luck.

It gives me a dialog box saying 'success' on boot and also when adding adding 
a service. I see no kpf errors in the standard places, but I'm still looking.

By default AFAICT libdns_sd is disabled, I did not enable it, and I confirmed 
on compilation it is not enabled. And I did compile and install 
kdnssd-avahi - hopefully correctly - per the konqueror / avahi wiki when I 
got started. 

Trying to simplify the problem, I tried a non-kpfs event such as:

/root> /usr/local/bin/avahi-publish-service "Robert's Apache" _http._tcp 80
Established under name 'Robert's Apache'

However, this command didn't turn up anything: 

/home/iksrazal/svn_avahi> /usr/local/bin/avahi-browse _http._tcp

Any ideas? Thanks!
