You mean, if xz is actually in FreeBSD 7, which doesn't seem to be the
case, is it absolutely necessary to disable builds of archivers/xz on
7?  Or, for that matter, on 8 and 9? -- well, no, it isn't strictly
necessary, but what's the point of not disabling the port when the
same version of xz is in both the base system and the port, and rtld's
default search pattern will favor the former over the latter?  With
the different versions of gcc, you are at least getting some
functional differences.  If naddy updates the port to 5.1.1 or 5.0.3,
the case might be different.
