Oh, yes, I saw that too now that you mention it.

is a rather fancy MacPorts-only addition to clang 3.9+ that allows fancy footwork with the c++ standard library. It gets added by the cxx11 PortGroup. For that to work, you need clang-3.9. (although I have it working with clang-3.8 myself, on PPC no less -- but that is another story).

clang-3.9 does work on 10.5, and works very well for me.
