I have the same problem as Chris on a 9-STABLE box.

I verified and re-verfied : kernel and world perfectly in sync; /usr/src
is a symlink but /sys points to the right place and (before patch)
/usr/share/mk/bsd.own.mk and /usr/src/share/mk/bsd.own.mk are
indentical.

Still I have to apply something like the following patch to get
VirtualBox kernel module compiled (no idea who/where MK_CLANG_IS_CC
gets set to "no", AFAIK not by me (I don't use src.conf and nothing
about CLANG in make.conf).

FYI, best regards, Arno
