 When I did that, I got
 {{{
 $ port deps opencv3 +openmp
 Full Name: opencv3 @3.4.16_1+openmp
 Build Dependencies:   cmake, pkgconfig, clang-13
 Library Dependencies: ffmpeg, zlib, bzip2, libpng, libjpeg-turbo,
 openjpeg, tiff, webp, ilmbase, openexr,
                       libomp
 $
 }}}
 which seems correct. But I'd prefer to use Xcode clang for everything that
 can be built with it, reserving Macports clang for things that have
 "special needs". I'm afraid the above {{{default_compilers}}} would
 compile all the Macports source ports with macports-clang-13...?
