Yes. Here is part of the bash profile

export CC=/Developer/usr/bin/llvm-gcc
export CXX=/Developer/usr/bin/llvm-g++
export OBJC=/Developer/usr/bin/llvm-gcc
export F77=/usr/local/bin/gfortran
export FC=/usr/local/bin//gfortran
export CFLAGS="-std=gnu99 -m64 -O4 -Wall -fopenmp -mtune=native"
export CXXFLAGS="-m64 -O4 -Wall -fopenmp -mtune=native"
export OBJCFLAGS="-std=gnu99 -m64 -O4 -Wall -fopenmp -mtune=native"
export FFLAGS="-m64 -O4 -Wall -fopenmp -mtune=native"
export FCFLAGS="-m64 -O4 -Wall -fopenmp -mtune=native"
export LDFLAGS="-m64 -fopenmp"

I haven't done any timing comparisons (yet).
