Comment (by mojca@…):

 I still agree that we probably want to talk to the developers, but I went
 ahead and applied a patch r120890 to `perl5.20`. Given that the port is
 completely new anyway, we won't break anyone's functionality and if the
 idea turns out not to work ... well then we can revert it.

 The problem with upstream is that they have a different model of
 installing and using Perl than MacPorts does and I understand why for them
 the model works and why they wouldn't want to switch to what I did, at
 least not by default. One installs one version of perl and keeps it there
 even after installing the next new version. But MacPorts removes the old
 version (and doesn't provide experimental versions) and there's where the
 problems start.

 We need to make a strong case and request a new feature, so that they
 would add a new configure option.

 I would suggest to apply the same change also to `perl5.18`. (Or maybe
 we'll change the way Perl works altogether anyway.)
