 FWIW I use my own GCC packages for those builds because I disagree 
 strongly with the way the pkgsrc packages are done.  My builds use these 
 two packages:
 
    https://github.com/TritonDataCenter/pkgsrc-extra/tree/main/gcc14-macos
    https://github.com/TritonDataCenter/pkgsrc-extra/tree/main/gcc14-macos-libs
 
 to ensure that the package is fully Darwin compatible, does not have any 
 unnecessary patches for other OS applied to it, and also so that there 
 is proper -libs package support for all Fortran packages, thus avoiding 
 the huge gcc runtime dependency.
