We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
import gensim fails since updating to Xcode 7.3 
I just updated my version of Xcode to 7.3. When I run `pip install --upgrade gensim` the process completed without any issues. However, when I try `import gensim` within the python shell the terminal barfs a bunch of C++ output with a block of execution errors that begins with: 

`Exception: Compilation failed (return status=1): clang: error: unsupported option '-b mi2'. clang: error: unsupported option '-b mi'. clang: error: unknown argument: '-target-feature'. clang: error: unknown argument: '-sse4a'. clang: error: unknown argument: '-target-feature'. clang: error: unknown argument: '-target-feature'. clang: error: unknown argument: '-target-feature'. clang: error: unknown argument: '-tbm'. clang: error: unknown argument: '-target-feature'. clang: error: unknown argument: '-target-feature'....`

I think this has something to do with where gensim is looking for its header files, but I'm somewhat at a loss. Any help debugging would be greatly appreciated.
