Clang >= 3.7 no longer ignores -fopenmp which now requires libomp.so from devel/openmp (for base compiler) or devel/llvm* built with OPENMP=on. For example: 1. Use FreeBSD >= 11.0 2. Install graphics/ImageMagick with OPENMP=on 3. Deinstall devel/openmp (just in case) 4. Build the port with default compiler The obvious fix is teach ImageMagick to not pollute namespace as nothing in its public API uses #pragma omp or omp_ symbols.
