New description:

 It appears that Graphviz @12.2.1_0 on Sequoia needs a newer compiler on
 ports version Version: 2.10.5.

 Using clang 19 from ports as in:

         sudo port install graphviz configure.cxx=clang++-mp-19

 makes it compile again (otherwise it would error out with a
 "configure:19965: error:  A compiler with support for C++17 language
 features is required." after it could not compile "conftest.cpp:450:10:
 fatal error: 'initializer_list' file not found").
