Comment:

 The Portfile uses [source:macports-ports/science/molden/files/patch-
 makefile.diff a patch] which fixes many problems in the build system,
 among them changes I described at the top of the patch like this:

 {{{
 Add -Wno-implicit-function-declaration to fix errors like the following
 with
 Apple Clang 12 and later and LLVM.org Clang 16 and later:

 error: implicit declaration of function 'mkcon_' [-Werror,-Wimplicit-
 function-declaration]

 The separate ambfor makefile already does this. This makes the port
 potentially incompatible with the arm64 architecture. This project has a
 zillion implicit function declarations which it is too much work for me to
 fix myself; the developer should do it. This has been reported to the
 developer by email but they have not reacted.
 }}}

 Until the developers fix the software to compile without `-Wno-implicit-
 function-declaration` I am not comfortable enabling support for arm64.
