Right now this requires LLVM to parse mach-o's and get symbols from them. Hopefully we'll make it a bit more modular in the future so it doesn't depend on LLVM (since it is a big compile/install)
To get this working:
Download llvm source tree from http://llvm.org/releases/3.9.0/llvm-3.9.0.src.tar.xz (or newer will probably work fine).
cd llvm-3.9.0.src/
mkdir build
cd build
cmake ..
make && sudo make install
Then you can successfully compile this project with just make.
