I use the compiler from the att site. It does support the arch flags, as they have applied the patches. They also explicitly state why you should not use the gfortran from the HPC site. I avoid all MacPorts compilers, as they make some bad packaging mistakes, such as linking against their own version of the c runtimes.<br>

Has a great distribution of gfortran based on each Xcode distribution. It seems to work well with CMake. Not sure about the -arch flag though.<br>
