The same warning tormented me for the longest time.  I figured out
how to fix it just the other night.

First, I searched the `pkg_info -aB` output for i386.  That showed
me that I had both pkg_install-20101122 and pkg_install-20200701
registered as installed.  The former was built for i386, and the
latter for amd64.  You may find that your system is in a similar
state.

I could find no i386 executables on my system:
the pkg_install-20200701 content had overwritten the pkg_install-20101122 binaries.
Since pkg_install-20101122 is used for installing packages, and
it was the *only* package built for i386, I guessed that the mere
fact that it was registered was the problem.

It took a little while to figure out an incantation that would
remove pkg_install-20101122 without erasing any pkg_install-20200701
content, since that would leave my system in a bad state.  Complicating
matters, both versions of pkg_install were registered as must-not-delete
packages.

I thought `pkg_delete -fN pkg_install-20101122` looked like a safe
candidate.  I tried it.  It worked.  No more warnings.

Maybe my fix will work for you.  It will be inconvenient if you
end up without any pkg_install whatsoever, so proceed cautiously.

I haven't seen this one.
