The next, and most common cause of avahi-related problems is that the
mDNS port, udp 5353, is not open in the firewall. Try

    avahi-browse -rt _pmcd._tcp

That returns nothing. But there may be a disconnection of understanding here. I am expecting that pmfind will find pmcd on the local host which should not involve the firewall (or rather the firewall should not get in the way). If pmfind is only looking externally, then the QA test is pathologically broken ... it will only work in an environment where some _other_ host is also avahi-enabled and accessible via multi-cast udp packets.
No, the test is expecting to find a local pmcd. No external one needed. I just suggested looking at the firewall in case it does cause a problem for local lookups on your platform.
