I'm building from Xcode, so I guess I need to change scripts/build-llvm.pl. Xcode reports this when I build:
% cd '/Users/felix/Projets/OpenSource/lldb/llvm-build/Release+Asserts/x86_64' && '/Users/felix/Projets/OpenSource/lldb/llvm/configure' --enable-targets=x86_64,arm --disable-terminfo --enable-cxx11 --enable-optimized --enable-assertions --enable-libcpp --build=x86_64-apple-darwin11 --enable-cxx11 is there, but even with that build completing successfully I still get the same error.
