（2）USE="mdnsresponder-compat" emerge avahi
然后再执行emerge --update --deep --newuse world时又要重新安装avahi，我查了下avahi安装时去掉了mdnsresponder-compat，

emerge --pretend avahi

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R   ] net-dns/avahi-0.6.24-r2

USE="mdnsresponder-compat"最好写到package.use里面：net-dns/avahi mdnsresponder-compat

OK了，多谢
