I think that's irrelevant for my use case.  I'm not building anything.
I was ugrading using the pre-built packages.

I don't know about actually validating references, but if you run 
"pkg_info -B ... | grep REQUIRES"
it will show you what actual library files a package needs.

The commands run just fine now, once everything got updated.  I don't
get any errors about libffi.so.6 not found, so I think it was just during
the trasition period while some packages were updated, but others were
not.

I think the recovery might actually require re-installing everything that
had a problem, to get each package's install scripts to run again.  Some of
the commands that I ran manually to get things working are things that I found
in the install scripts, but I don't know if there is anything else I missed.
