^^ your Intel libs (or at least libiomp5) are missing paths in the id string - probably not installed properly? You can hack around that using DYLD_FALLBACK_LIBRARY_PATH but it's better to fix the issue in libiomp5 directly.

I don't think you should put them in manually. The actual error comes from missing libguide link flags, but they may be implicit if you fix the other problem.
