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
