I did a major OSX update (from 12.x to 15.3 ...) and have run into this problem after having update
the Xcode command line tools and issuing port migrate.
the graphiz package (which is a dependency of the `feh' image viewer which is the actual package I
do need) refuses to install:
:info:configure checking whether /usr/bin/clang++ supports C++17 features with
-std=c++17... no
:info:configure checking whether /usr/bin/clang++ supports C++17 features with
+std=c++17... no
:info:configure checking whether /usr/bin/clang++ supports C++17 features with

:info:configure configure: error: *** A compiler with support for C++17
language features is required.
I do see this with
clang --version
Apple clang version 16.0.0 (clang-1600.0.26.6)
and I believe this is as it should be with OSX 15.3?
my question: can this be fixed on my side or is this a principal issue
currently?
thank you
