What tar is this?

(Note: this is --use-compress-program, not --use-_de_compress-program)

GNU tar supports --use-compress-program since at least 2004.

The tar in MacOS-X does document this option:
https://developer.apple.com/library/mac/#documentation/Darwin/Reference/Manpages/man1/tar.1.html

The -J was introduced 2008-12-27 in GNU tar, so it is not supported by
Debian Lenny (the previous stable, still widely used), so this can't be
used. --lzma is also relatively recent, it was added 2008-04-14 (still
in GNU tar).

The tar in MacOS-X supports neither -J nor --lzma, so neither is portable.
