Perl _was_ set up to be threaded (although I have no idea what is actually
threaded there), but the port option to enable it being threaded was not
enabled by default. The implication is that if you compiled it with default
options, it wasn't threaded. But now it (the option) has been changed to be
enabled by default, and so the point of that UPDATING entry was that if you
are running with default options, then your Perl will switch from
non-threaded to threaded when you recompile it, and you will thus need to
recompile all ports that depend on Perl.
IF you already had this option enabled to begin with, I believe you don't
need to recompile and reinstall anything (including Perl itself, but do
note that the ports system will then keep thinking that Perl hasn't been
upgraded - which isn't an issue, since the only thing changed here is the
defaults and not any functionality, and so you can just wait to recompile
it when something more serious changes; this is up to you though).

Hope this clears it up a bit.
