thanks a lot to both of you. this (https://trac.macports.org/wiki/ProblemHotlist#clts16) was indeed
it. very much appreciated! also thanks a lot for constantly improving macports which has come a long
way over the last 10-20(?) years :). `port migrate', e.g., nowadays makes life a lot easier and
seemed to have worked mostly flawlessly today for me.
best,
joerg
ps: could/should not https://trac.macports.org/wiki/ProblemHotlist#clts16 be somehow integrated into
the `port migrate' actions? it seems it is a general pitfall currently, no?.

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

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?
