nope. i can't even telnet to 127.0.0.1:4949 or to $hostname:4949 (so the
munin server can't connect to gather data).

as i said, i can force munin-node to listen on a single ipv4 address
with 'host ip.ip.ip.ip' in /etc/munin/munin-node.conf but if that
setting is left at the default 'host *', then it will ONLY listen on
ipv6 addresses since libnet-server-perl was upgraded to 0.99-3

downgrading libnet-server-perl to 0.99-2 fixes the problem.
