Okay, I used avahi-discover to copy the info from a shared printer on a Snow Leopard \
system to create my avahi service file. Another OS X system picked it up from Avahi \
just fine, but failed to print until I changed the path in the CUPS from \
ipp://path/to/printer:631 to http://path/to/printer:631. Then it works great, but not \
quite automagic.

Again I go back to CUPS Admin on the Mac printer share and see that there is a \
checked option for "DNS-SD" that I can't get on the Linux system.

I start digging through the sources and find reference to dns_sd libraries and find a \
package in YUM called avahi-compat-libdns_sd-devel and install it. But it still \
compiles without the DNS-SD option.

So I think that my fundamental problem is that CUPS is building without dns-sd on my \
CentOS 5.7 x86_64 system for some reason. Can anyone provide advice on how to get \
that feature included in the rpm from rpmbuild?

Thanks,

Cedric
