Thanks for the suggestion.  I looked at that, and was a bit put off by
the "(DEPRECATED)" warning in the pkg-set man page.  Well, that, as well
as the sense that I was treading in areas I understood but poorly, and
if I screwed up, I could lose Internet connectivity (at home, at least)
and/or the abiliity to send & receive email....  So I elected to wait a
bit.

Well, as I pointed out in the original note, I use portmaster on my
"development" systems (which I update daily), and poudriere/pkg on the
"production" systems (which I update weekly).

Thanks!  I merely figured I'd want to have a record of what I did, and
that such a record might be of use to others (if for no other reason
than to be able to avoid some of the things that I encountered).

OK; that appears to have worked as advertised -- thanks you!

(I do a "poudriere bulk" as part of the weekly upgrade in any case, as
I've updated the ports working copy, so the production machines do a
"pkg upgrade" just after updating base FreeBSD.)

So -- in my case -- the "short answer" was:
* Specify the local default in /usr/local/etc/poudriere.d/make.conf via:
  DEFAULT_VERSIONS+=     perl5=5.22
 
* Perform the usual weekly upgrade.

And "so far, so good" -- I have verified that I can send & receive
email, at least, and other stuff seems OK so far. :-)

Huh; interesting: thanks.  I may poke at that after I have occasion to
power up the build machine again (probably not until tomorrow).

Thank you both for your guidance!

Peace,
