For reasons which are entirely unguessable, the man-page for avahi-daemon(8) shipped with avahi-app-0.6.31 (the latest version in ports, as of writing) have erroneous paths listed: Example location taken from man avahi-daemon(8): /home/lennart/tmp/avahi/usr/local/etc/avahi/avahi-daemon.conf Expected location: /usr/local/etc/avahi/avahi-daemon.conf Actual location: /usr/local/etc/avahi/avahi-daemon.conf Since this is fixed in avahi-app-0.6.32 (Although it isn't mentioned in the ChangeLog, I verified it by looking at the man-page from avahi-app-0.6.31.tar.gz; additionally also fixed in avahi-app-0.7 which has since been released), perhaps the port should also be updated?
