Is it semptools -> semPlot -> OpenMx?

The situation is indeed suboptimal, because while it's easy to install
a binary build of the previous version of OpenMx for r-oldrel from
CRAN, installing a compatible version of OpenMx from source requires
visiting <https://cran.r-project.org/src/contrib/Archive/OpenMx/> and
resolving dependencies manually, one by one. (There's no dependency
index of archived packages.)

The latest version of semPlot does seem to work with the old version of
OpenMx, seeing as it passes the r-oldrel checks. I think that the
r-oldrel builders and checkers on CRAN won't notice any problem with
semptools either, because they still have the old version of OpenMx
installed.
