Hi,

I'm pretty sure your problem is connected with the fact that
according with manpages, in 8.X, the tar tool ignores the lzma
compression format (.xz), probably introduced during an upgrade
between 9.0 and 9.1.

You should notify that to the port maintainer to introduce a bypass
for the FreeBSD 8.x versions.
