Do we know which host versions are lacking?

No; clang (from MacPorts or Xcode or compiled by hand) will use the system’s C++ runtime, unless you tell it otherwise; same goes for llvm-gcc and Apple’s modified versions of gcc, regardless where you got them. The only compilers we have that automatically use their own C++ runtime are the FSF versions of gcc, and somehow I don’t think telling them to use a different C++ runtime would be very successful.
