The problem has to do with my inability to understand/use Python ...
the host I'm using has python3 == 3.9, which I think isn't new enough.
At one time I had been using pyenv to get access to a newer version,
but this was somehow overriding PATH and replacing whatever java I
configure with /usr/bin/java (which is some ancient version on this
system).  So I think this has nothing to do with Lucene, it's just
some horrible setup.  I need to run the smoketester somewhere else or
get the system working better I guess
