I have been doing this (on a daily basis) with both head & stable/9 on
my home "build machine" and my laptop since 12 Jul 2012; I have seen no
problems or issues.  (I build my ports under stable/8 & have /usr/local
in common across all 4 slices on each machine.)

Here's what's in my /etc/src.conf for stable/9:

CC=clang
CXX=clang++
CPP=clang-cpp
WITH_LIBCPLUSPLUS=yes

When I update my "production" machines at home from stable/8 to stable/9
(probably shortly after 9.1 is released), they will (by necessity) also
migrate to FreeBSD built with llvm/clang (as they get installed what the
build machine builds).

Peace,
david
