>Description:
        archivers/xz (xz-4.999.9beta) fails to compile on NetBSD 4.0 (i386).
        Problems relate to sysctl.

>How-To-Repeat:
        I use pkg_comp with NetBSD 4.0 sets installed, and libkver, to
        obtain a fairly pure 4.0 release environment.   No x* sets,
        this setup uses pkgsrc modular xorg instead (I doubt that is
        relevant).
