Put another way, Avahi's compat layer writes out a bogus error to
stderr which is guaranteed to cause problems.  What the Avahi
developers can do it either a) fix their compat layer or b) remove
their compat layer if they don't want to support it.  What Linux
distributors can do is add --disable-dbus when building CUPS until
the Avahi folks make up their mind about whether they want to support
Apple's original DNS-SD API.
