Thank you very much, -DRT_ARCHIVE_WITH_LDC=OFF was the missing 
argument to make it work on OSX.

I wanted to switch to ldc 1.6.0 but got the following error.
First I tried with llvm 4 but since you mentioned llvm 5 I tried 
it but without succes. I got the same error as with 4.

CMake Error at runtime/jit-rt/DefineBuildJitRT.cmake:40 (include):
   include could not find load file:

     
/nix/store/n0yi0jz38k67zmpn86zixyizhscb1c7d-llvm-5.0.0-lib/lib/cmake/llvm/LLVMConfig.cmake

Maybe the llvm packages in Nixos have this file missing but since 
I don't know anything about llvm internals I can't tell.
It seems strange though because I think a missing file should 
have been detected by other packages depending on LLVM.
The build derivation for llvm 5 can be found under 
https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/compilers/llvm/5/llvm.nix though. Maybe there are some missing flags or something?
