Let me elaborate it a bit:

pdnsd is a DNS server capable of listening on TCP/UDP ports (depending
on options in configuration file and commandline). Options set on
commandline override what is set is configuration file. And, in init
script of this port, the option to listen on TCP ports, i.e. '-t'
switch, has been explicitly passed. So, there is no way, one can disable
listening on TCP from pdnsd.conf. So one, has to edit '/etc/conf.d/pdnsd'
and add --notcp option. In my view, from the point-of least privileges,
one has to explicitly turn on listening of daemon on port.

So its a problem on Gentoo porting side, not with the pdnsd team.

Thanks.
