This problem has reared its head in perl 5.14.2 on FreeBSD 8.3 in the execution of postgrey. Turning off taint checking makes the error go away. postgrey --inet=10023 --pidfile=/var/run/postgrey.pid \ --user=postgrey --group=postgrey --dbdir=/var/db/postgrey 2013/03/27-08:53:46 postgrey (type Net::Server::Multiplex) starting! pid(45305) Resolved localhost:10023 to ::1:10023, IPv6 Resolved localhost:10023 to ::1:10023, IPv6 Resolved localhost:10023 to 127.0.0.1:10023, IPv4 Resolved localhost:10023 to 127.0.0.1:10023, IPv4 Duplicate configuration (TCP) on ::1:10023 with IPv6) - skipping Duplicate configuration (TCP) on 127.0.0.1:10023 with IPv4) - skipping Binding to TCP port 10023 on host ::1 with IPv6 Insecure dependency in socket while running with -T switch at /usr/local/lib/perl5/site_perl/5.14.2/mach/IO/Socket.pm line 80. Is the bug in perl itself or in the perl modules it calls? All have been rebuilt and reinstalled from source in the past few days to ensure nothing was damaged or out of date. FWIW, it doesn't happen if you choose the unix domain socket but then you can't daemonize the process on the command line: you can add an & but you can't use the -d argument.

The underlying issue was something of a reincarnation of CPAN hell: stale ports which included outdated, taint-dirty code that produced a namespace conflict with current base code. Once the old ports were removed and the local perl install recreated with only those ports needed as dependencies, postgrey began working normally.	[reply]
