OK, so it looks like we need:

"-stdlib=libc++"

and maybe:
-mmacosx-version-min=10.6

But shouldn't ditutils have already done that?

And some folks seem to say that if macosx-version-min is set, then
you shouldn't  need the stdlib setting -- so maybe the pythonorg builds
will still work

NOTE: I'm not sure what Python build the user in question was using -- if
it's macprot, or homebrew or raoll-your-own, then the macosversion may not
have been set.

Thanks,
  -Chris
