Comment (by MSoegtropIMC):

 I am still struggling to understand what is going on. I have:
 {{{
 :debug:configure Preferred compilers: clang macports-clang-9.0 macports-
 clang-8.0 macports-clang-7.0 macports-clang-6.0 macports-clang-5.0
 :debug:configure Using compiler 'Xcode Clang'

 :info:build -- The CXX compiler identification is AppleClang
 11.0.3.11030032

 }}}
 and
 {{{
 wxmaxima$ which clang
 /usr/bin/clang

 wxmaxima$ /usr/bin/clang --version
 Apple clang version 11.0.3 (clang-1103.0.32.59)
 Target: x86_64-apple-darwin19.4.0
 Thread model: posix
 InstalledDir: /Library/Developer/CommandLineTools/usr/bin
 }}}
 I would think either this is a bug in MacPorts itself or your
 /usr/bin/clang is not the Apple Xcode clang.

 Can you please check what the two above commands give for you, so that we
 can exclude the latter?

 Another thing which I think is strange that the preferred compilers fo not
 list Xcode 10 and Xcode 11. Does someone have a good explanation for this?
