It looks like this was caused by Maxim Sobolev's workaround here: http://lists.freebsd.org/pipermail/cvs-ports/2012-April/240000.html He attempts to set MK_ variables by hand, but that is obviously not allowed. As has been said before, it is indeed possible to put a workaround for compiling with the wrong source directory in bsd.own.mk, but that would really help people to shoot themselves in the foot. It looks like the virtualbox-ose-kmod port sets a SRC_BASE variable to the appropriate source directory, but it should probably also set the MAKESYSPATH environment variable to ${SRC_BASE}/share/mk before invoking make. Note this is still not 100% safe, as you would really need to build using a toolchain corresponding to your kernel sources, but it's better than nothing.
