It recently came up that base should always add the macports-gcc compilers to the fallback list on ppc. What's less clear is what should be done on Intel 10.5 and 10.4.
Does anyone know with certainty: 1. Which versions of macports-clang (if any) work on these platforms without any LibcxxOnOlderSystems modifications? 2. Which versions of macports-gcc work well on these platforms? - Josh
