maybe I'm doing the wrong thing by adding use lines for test modules
that unit tests use.  maybe there's some magic that's supposed to
automatically use those things, even though they're hidden in deeply
buried paths with no machine predictable naming scheme.  I can't
imagine that these unit tests passed before unless there is/was
some magic.  I hobbled this in to working with a use lib and a
use for the module, but after doing this second one of these,
I'm having serious doubts about whether I'm just spackling over
the problem.
