 This Clang is too old. `libstdcxx` requires at least clang-425.

 Did you specify those compilers when trying to install?
 {{{
 sudo port install libstdcxx +universal configure.compiler=macports-llvm-
 gcc-4.2
 sudo port install libstdcxx +universal configure.compiler=macports-
 clang-3.3
 }}}
 In the current MacPorts release, the compiler fallback list for Xcode 3.2
 is gcc-4.2 > clang > llvm-gcc-4.2 > gcc-4.0 > apple-gcc-4.0, so none of
 the compilers you tried would have gotten picked up automatically.
