I remember similar deep blocks myself - it was nasty at the time. For the OP's benefit, here's a high level summary of what is going on: Avahi and mDNSResponder implement a system called ZeroConf, first designed by Apple. It's a way for machines on a network to find each other and what network features they support. These systems are quite low-level so unfortunately the implementations are often incompatible. By and large you will find that Gnome stuff supports Avahi and KDE stuff supports mDNSResponder, so the only way out of this mess is often extensive use of 'equery hasuse', 'equery depends' and 'emerge -pvt' so see what pulls in what. But first you should research what these things are so you can make intelligent decisions about what to include and what to drop. The thing that cleared it up for me was an interview with the KDE team lead responsible for these features - Google will find it for you. Personally, I find these things more trouble than they are worth. They seem to be designed for the "Apple Generation User" (whatever that is), and I have no use for that on the networks I work on. ZeroConf is not necessarily something you have to have installed... -- alan dot mckinnon at gmail dot com
