I cycled through apt-get install and 'remove --purge' for maria-db and the
pdns-backend-mysql. (The host I'm experimenting on is busy with a separate
experiment, so I haven't gone as far as a reboot. Yet.)

Yes, but as I tried different permutations, the errors were "dancing" around.
The root cause is that I didn't install things in order, and I'm not even sure
what version (in general) is installed with the apt-get.
(A question: does "pdns-backend-mysql" define a/the schema PowerDNS expects in
a database?)

Yep, 16.04, and apt-get is installing something with "alpha" in the name
(always a bad sign). I wish I had known about the repo earlier, web searches
[how I began] didn't turn up a link to that.

Thanks.
But I have to declare temporary failure. While I'd like to master building
PowerDNS, I have a time constraint. I'm preparing training DNSSEC materials
for a ccTLD. The DNSSEC side I know, operations I understand. It's just that
they told me last week they use PowerDNS. Now my 'fear' is that they will have
a different PowerDNS set up in place from what I am hoping to build and
anything I generate now, if I could, might be different enough to be unhelpful
in the training.
It would be unfair to compare to BIND here - which I've used for 20 years - but
it has spoiled me in the "one tar-ball" installation. (Of course, BIND's code
base is a hairball.) And I've worked with NLnet Lab's unbound, that though
took years before I could build it on my available platform (MacOS). I'm not
surprised that building open source packages takes work.
I also realize that for an open source effort, keeping all the documentation,
especially user guides is a monstrous effort and what doesn't help are out of
date webpages (by others) giving "old" advice.
PS - What's floating around in me is Lua or Lua2...I bet the operator is using
that, so me playing with mySQL might not be the best use of my time.
