Comment (by RobK88):

 I am building with `+gfortran+openblas` since they are the default
 variants.

 You are right, builindg with just `+gfortran` made no difference. The
 build failed since the `py311-cython` libraries could not be found.
 P.S.  I also tried `sudo port install py311-numpy +gfortran -openblas`.
 Same error.

 I will try debugging as you suggested and will get back to you.
