You need to build Clang/LLVM with a {CXX, CXXFLAGS} pair (read: a c++ compiler 
for your host) that supports C++11. That can either be one whose default is 
c++11, or one that doesn't but lets you put '--std=c++11' in the CXXFLAGS.

http://llvm.org/docs/GettingStarted.html suggests GCC >= 4.7.0 for this.
