What have I forgotten about specifying which Perl should be /opt/local/bin/perl?

I had to glance back and forth a couple times there. I… guess you're

Yes, that was exactly the syntax I didn't remember and couldn't recall
enough of to locate in the man page. Thank you!

Modifying them to use the select mechanism (and more specifically modifying every port that currently depends on port:perl5 or path:bin/perl:perl5 to use a specific version of perl) would be a large undertaking, and I'm not sure the benefit would outweigh the drawbacks and the effort involved.
Oh, for sure!
I'm… also not sure it's even actually a good idea, since, in my
experience, Perl is much more flexible about newer versions of `perl`
functioning with "out-dated" versions of libraries *and* vice versa
than, say, PHP is. (I think maybe Python plays better with
Ahem: Perl is more flexible, so having more than one version (including
whatever Apple deigns to stomp all over `/usr/bin/perl` with in any
given release) around only *really* matters in corner cases, even if you
take the (questionable: I've made this choice under NetBSD and concluded
it was probably a mistake) decision to tell all installed versions about
the others' LIBPATHs (while having each version's CPAN module control
only its own).
By "flexible", I mean it'll *try*, and well-designed modules will keep
traversing the library path till they find a version that'll work for
them, but that takes some gymnastics few modules implement in the real
But also that trac ticket's been around for 11 years, and has a lot of
interest, including recently, and I'm currently unemployed. So… hm.
I only skimmed the ticket just now (and will read it in more detail,
because I'm interested), but do you know of prior embarkations down this
It is, demonstrably (the responses to that ticket), a UI/UX wart.

over to macports-dev, if you think either's more appropriate.)
