I don't believe we do require it. macOS ships bsdtar (that is, the one from libarchive) and to the best of my knowledge, everything works fine there. I suspect the reason that gtar is preferred is because on some systems, the tar(1) command is relatively incapable and doesn't support things like POSIX tar archives or pax extensions. -- brian m. carlson (he/him or they/them) Houston, Texas, US
