Yes, what I meant about building your own installation of emscripten is building LLVM and BInaryen and the other tools yourself. There shouldn't be any need to do that. In particular, if you get your checkout of LLVM and the rest of the emscripten tools from different places I would not expect them to work together correctly. That is why you are seeing errors when trying to use the tools. Using emsdk will get you a complete installation of emscripten that does not require you to build anything yourself and it should not have any of the issues you are seeing.
