One immediate problem is that Julia comes with patches for LLVM 3.9 only: https://github.com/JuliaLang/julia#llvm
it downloads, patches and compiles a specific LLVM. We actually need this even though the failing tests are possibly not related (I suspect the math libraries are not showing the same results as the built-in ones). I think we need to follow the recommended build steps for Julia first. Then the tests should pass. Next perhaps link out components and send bug reports upstream. Pj.
