The build failure is in libomp, which has the following compiler whitelist:

    # According to documentation builds with clang >= 3.3
    compiler.whitelist      clang \
        macports-clang-3.3 \
        macports-clang-3.4 \
        macports-clang-3.5 \
        macports-clang-3.6 \
        macports-clang-3.7 \
        macports-clang-3.8 \
        macports-clang-3.9
