From on and offlist comments, the consensus is that our pax does not
understand newer format headers that are appearing, and hance pax-as-tar
(NetBSD <= 8) does not either.

Thus, packages like this need to use gtar or tar-with-libarchive, found
in NetBSD >=9.

Moving to tech-pkg to talk about how best to do this.
