--- Comment #55 from howarth at bromo dot med.uc.edu --- (In reply to Derrick Kay from comment #53) If you just want the gfortran compiler for Yosemite, either install the gcc49 package under the fink (http://www.finkproject.org), MacPorts (http://www.macports.org) or homebrew (http://brew.sh) packaging systems. Also, a stand-alone installation of gfortran for Yosemite is available at http://hpc.sourceforge.net.
