Comment (by kencu):

 I'm going to try a different, more comprehensive approach to this issue. I
 patched macports-clang-3.x to default to `-stdlib=libc++` instead of
 `-stdlib=libstdc++` on all systems, including 10.6.

 So far, it fixes the issue with botan, and I think it will also solve the
 wx-widgets issue and the leveldb issue as well.

 Will see how it goes. If it works well, Jeremy can decide if that's
 appropriate or not for general use.
