I just wanted to share this with the group.  While I found Xcode - Homebrew directions, I didn’t find any Xcode - Macports directions.

This brief set of steps worked for me.

1. In Macports, I installed llvm clang 3.7 with openmp support:

	sudo port install llvm-3.7

	sudo port install ld64 +ld64_xcode

	sudo port install clang-3.7 +openmp

2. In Xcode project, I added user-defined settings ‘CC’ with value set to “/opt/local/bin/clang-mp-3.7”  (clang path).

3. Add “-fopenmp” to “Other C Flags”  

4. Open folder “/opt/local/lib/libomp” and drag libomp.dylib to Xcode project.  This will add the library to the project.

5. Test openmp functionality.

Hope this helps,
