libtorrent-rasterbar @1.2.4: error: invalid value 'c++14' in '-std=c++14'

[ryandesign (Ryan Carsten Schmidt)]

libtorrent-rasterbar indicates that it requires C++14, so on Mavericks MacPorts chooses a newer MacPorts compiler. However libtorrent-rasterbar is not UsingTheRightCompiler for everything, so some parts are still building with /usr/bin/clang ​which fails:
