I built and updated FreeBSD based on that vintage
and the port builds are part way through. The ports
that I had observed problems for have built just
fine and no others have failed so far.

If it all builds, it will be tomorrow sometime before
the bulk builds finish. But I figured I'd indicate
that the fix looks to have fully worked for my
context that had the problem.
