Yeah, I still smile and shake my head in amazement, especially on a
screaming-fast machine.

Not that I know of other than going to CPAN and manually downloading
the preferred older version, and doing the usual four-step process
(perl Makefile.PL, make, make test, make install) manually.

That may be a good reason to use the "ask" option to following
dependencies, especially if using an older version of Perl.  If it
wanted a newer version of some module that's bundled with Perl, then
it will happily upgrade Perl for you.  I have to say I prefer to do
that one manually.
