· installing an older version of a port in the github era -- an answer https://lists.macports.org/pipermail/macports-dev/2016-December/035058.html · set port not to upgrade https://lists.macports.org/pipermail/macports-users/2017-February/thread.html#42751 · Local Portfile Repositories https://guide.macports.org/#development.local-repositories I haven't gotten around to make it with git, nor used local libraries yet, but you could try duplicating libarchive and cmake locally and make the latter dependent on a renamed version of the former, like port:libarchive_local in its portfile. For the caveats read the threads above.
