Of course, on a newer OS, this just isn't a problem. :-) But that old 2007 Mac Mini can't go past Lion anyway, and Snow Leopard has the advantage of being the last version that can still do Rosetta, so there's no incentive for me to upgrade it to Lion and lose that capability.</div><div class=""><br class=""></div><div class="">Perhaps some of those will now no longer be needed, if the corresponding ports find and use the macports-clang-3.8 by default, if available.
