What bit me in the process was that the "Cross Building Using The Host Cross Compiler" section had to be followed to a T - in particular, the built cross toolchain in /usr/obj/usr/src/tmp must be moved to <chroot_root>/usr/obj wholesale, the local headers symlink made, and the cross-CC environment variables set up. The error in #2 above seems to indicate that the cross tool is not statically linked, so maybe the wrong toolchain is in use. The second gotcha turned out to be the mysterious-sounding "Add the miscellaneous binary image activator patch to FreeBSD" section. I didn't understand what that was for till various python scripts that start with shebangs (#!/usr/local/bin/python2.7) would fail to be loaded as python scripts. Invoking the image activator magic allowed that part to be solved. Regards -T.W.Chan-
