Hi Brooks,

Both old and new package will be installed in version specific
directories, so no overlap will occur and the versions can be used and
run simultaneously.

The problem is how to detect whether portupgrade is being used to run
the pkg_delete, or whether pkg_delete is being run directly from the
command line. Is this supported, or is there some good or recommended
way of doing this?
