In /etc/make.conf add -
CC=/usr/local/bin/clang33
CXX=/usr/local/bin/clang++33
CPP=/usr/local/bin/clang-cpp33
If you find a port that has trouble with that you can add
.if ${.CURDIR:M*/math/atlas*}
USE_GCC=any
.endif
you can swap any for a specific version number
eg- USE_GCC=4.8
Or you can go the other way and specify which ports use clang33
