Comment (by Schamschula):

 Indeed: At the tip of the iceberg, {{{configure}}} fails, because it's
 looking in the wrong place for libfortran

 {{{
 configure:13431: /usr/bin/clang -o conftest -pipe -Os
 -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -arch arm64
 -I/opt/local/include
 -isysroot/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
 -L/opt/local/lib -Wl,-headerpad_max_install_names
 -L/opt/local/libexec/qt5/lib
 -Wl,-syslibroot,/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk -arch
 arm64 conftest.c -lm  -L/opt/local/lib/gccdevel -lgfortran -lm >&5
 ld: warning: directory not found for option '-L/opt/local/lib/gccdevel'
 ld: library not found for -lgfortran
 clang: error: linker command failed with exit code 1 (use -v to see
 invocation)
 }}}

 {{{gcc-devel}}} installs its libs in {{{/opt/local/lib/libgcc/}}}
