Comment (by kencu):

 So - a workaround, again, but what we really need is a proper portfile
 fix. I defer to g5pw, but it would appear that ostinato needs some newer
 clang version than the clang-3.4-ish version that comes with 10.8. But to
 make it build with this newer clang version, it looks like that needs to
 get baked into qt4 during the build of qt4-mac. This is a bit messy. Does
 the qmake portgroup take care of something like this?
