you should be able to set the value of CC in the environment, or pass it 
through as a Make environment variable to use your choice of compiler...

normally you can execute:
CC=/usr/local/gcc-N.NN/bin/gcc make target

although with the BSD ports system, you may need to do it differently, 
either in the top level Makefile or via:
make -E CC=/usr/local/gcc-N.NN/bin/gcc
