 When upgrading outdated ports after upgrading from High Sierra to Catalina
 (without performing the complete uninstall and reinstall dance of
 wiki:Migration), I am seeing errors like this:

 This seems to happen only for those ports whose version, revision and
 variants exactly matched the previously installed one. It didn't happen,
 for example, for findutils, which had been installed with universal before
 but not now (since universal isn't possible on Catalina).
