net/avahi-app: I just need the daemon, how do I install that?

[Darren Pilgrim]

I've been going over the avahi-app Makefile and can't see a way to build 
and install just the daemon and there isn't a net/avahi-daemon port. 
Most Linux distros have an avahi-daemon package which correctly only 
requires expat, libdaemon and dbus.  I avoid dbus at all costs, so all I 
need is a way to build the daemon without dbus support.

I found this forum thread from 13 months ago:

Where is the daemon-only subport?  Do you have a patch or a subport PR I 
could look at?
