gdal @3.7.3 Fails to Build on Lion

[RobK88]

I am unable to upgrade gdal on Lion.

bash-3.2$ sudo port clean gdal
--->  Cleaning gdal
bash-3.2$ 
bash-3.2$ sudo port -v upgrade gdal 
--->  Computing dependencies for gdal.
--->  Fetching archive for gdal

etc etc

The workaround is to build using clang-16. It looks like gdal is yet another port that will not compile using clang-17 on Lion.
