py310-numpy @1.23.4 fails to build with py310-setuptools @65.6.0_0

[hmeine (Hans Meine)]

I am trying to sudo port install py310-numpy (on arm64, Ventura) with the following default variants:

py310-numpy has the variants:
   atlas: Use MacPorts ATLAS Libraries
     * conflicts with mkl openblas
   gcc10: Build using the MacPorts gcc 10 compiler
     * conflicts with gcc11 gcc12 gccdevel gfortran gfortran
   gcc11: Build using the MacPorts gcc 11 compiler
     * conflicts with gcc10 gcc12 gccdevel gfortran gfortran
   gcc12: Build using the MacPorts gcc 12 compiler
     * conflicts with gcc10 gcc11 gccdevel gfortran gfortran
   gccdevel: Build using the MacPorts gcc devel compiler
     * conflicts with gcc10 gcc11 gcc12 gfortran gfortran
[+]gfortran: Build using the MacPorts gcc 12 Fortran compiler
     * conflicts with gcc10 gcc11 gcc12 gccdevel
   mkl: Use MacPorts MKL Libraries
     * conflicts with atlas openblas
[+]openblas: Use MacPorts OpenBLAS Libraries
     * conflicts with atlas mkl
   universal: Build for multiple architectures

but the build fails very quickly, apparently due to this error I found in the log:

I am puzzled by the capitalized "Log". Looking into /opt/local/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/site-packages/setuptools/_distutils/log.py, this is a very small compatibility module; maybe recent setuptools versions do not expose the implementation as much as previously, and numpy is no longer compatible with this.

I currently have py310-setuptools @65.6.0_0 (active).
