More to the point, it’s _still_ installable that way, and the current version’s
minimum Perl requirement is 5.3.0, from 1996:
https://metacpan.org/pod/Digest::SHA
If you had to pin to an old version of the package to get it to install, I’d
have less sympathy with this argument.

It’s a good bet, though.
The thing is, it *isn't* the Autoconf Way: test for features, not versions.
There is one good use case for “use v5.xx” in a Perl program: when you’re
requiring a particular version of the Perl interpreter, to use language
features that didn’t exist and couldn’t be patched in with packages before that.
This is not that case.
However, I will repeat a point from an earlier thread: the generated configure
scripts from the new version of Autoconf will continue running on these older
systems. The only thing being broken is the ability to *generate* configure
scripts with Autoconf on those ancient systems.
