Seems libc++ is working only on OSX, so it's still libstdc++ on Linux, so that's not it... or maybe it is. The libstdc++ shipped with Xcode is the last GPLV2 one and doesn't support C++11, so I can't test against it to see if that's the problem. Maybe this is the problem: https://bbs.archlinux.org/viewtopic.php?id=135667 Apparently clang isn't smart enough to figure out that it should compile a C++ file as C++, so you need to set $CXX=clang++.
