Hi,
Its difficult to say as you haven't provided enough information really
to help much. My guess would be you still perhaps have an issue with
your CLT installation, but that is just a guess. see
https://trac.macports.org/wiki/ProblemHotlist#clts16
If you still have issues after following the instructions there please
open a trac ticket with more complete information so someone can help
you further.
Just to note, graphviz (which I presume i what you really mean) builds
perfectly fine on macOS15
https://ports.macports.org/port/graphviz/details/
so there is no general issue but some issue local to your setup.

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:

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
joerg
