If you use gfortran: which version? If you are not using any floating point then gfortran-4.8 will probably work without problems. I think. > Anyone have some harder info on this?

The latter could be fixed by rebuilding the compiler. > As far I know the compiler binaries use/generate floating point instructions directly or indirectly that cannot be handled by a C2D. See this reply by Simon to my original post: https://stat.ethz.ch/pipermail/r-sig-mac/2014-May/010895.html Probably more than just the compiler binaries would have to be recompiled.
