Merci François for your efforts.

I have replaced the resp. library by my MacPorts build and it compiles now!
Perhaps a hacker way, however. Perhaps I install the compiler from MacPorts
after these experiences. And all that only to try openMP on Mac!

Still linking delivers now seemingly a followup-error:
Undefined symbols for architecture x86_64:
  "___cxa_throw_bad_array_new_length", referenced from:
      create_parameters_gui(bool) in cc2Df7NY.o
