Actually, I have an old FreeBSD 8.2 installation on a 40 GB IDE hard drive, MBR with legacy FreeBSD bsdlabel on MBR slice 4, not enough maneuvering space for any upgrading.

I had the later thought, pkg is also in NetBSD pkgsrc, maybe pkg convert in NetBSD, but I would be inclined to try only on a system already messed up sufficiently that there is nothing further to lose.

Or one can use pkgsrc (ouch!) with FreeBSD with old pkg_* tools and decide to switch to FreeBSD pkgng format.
