Thank you for taking a look.

It is not the same problem as fortran-lang/stdlib#807 . macos-13 runners have Intel chips, not Arm. Thanks.

Similar issue for me, with macOS and gfortran: https://github.com/danieljprice/phantom/actions/runs/9133304238/job/25117800865?pr=545

Update: I worked around this by simply installing gfortran with "brew install gfortran", there does not seem to be a need for the soft link workarounds anymore...

thanks all for the report, I think the issue is resolved on main and will plan to do a release and update the v1 tag soon
