Comment (by me@…):

 It occurs only when I try to install modules using the `cpan` command,
 which I've only done for modules that are not available as ports
 (specifically, IO::Socket::INET6).  If I can get cpan to work I would
 prefer the one-command install to the lengthy process on the wiki page.

 Judging by the responses on
 [https://rt.perl.org/Ticket/Display.html?id=121901 perl bug #121901], the
 problem is that the macports package `perl5 @5.12.4_0+perl5_16` includes a
 version of `/opt/local/bin/cpan` that is incompatible with perl 5.16.3.
 (My perl5.16 was installed as a dependency of perl5.)

 I have cpan version 2.05, but for perl 5.16.3 it should be cpan version
 1.98.
