I've not tried on the BBB, just Raspberry Pi. I should probably give it = a go on the BBB now I have a cross-built FreeBSD working on there.

I have = never managed to do a successful native build using clang; I always have = to set the compilers to point to the native GCC versions in my = /etc/src.conf. (I can, of course, successfully cross-build world and = kernel using clang via crochet.) Do you have a SVN revision number that will successfully build natively = using clang?
