Comment (by jrabinow):

 I can deal with port breakage, but I don't go around creating random
 symlinks. Stuff I build/download goes under `/usr/local` (fbinfer and
 docker) if no other choice, `~/bin` if I want it in my PATH, or stays in
 its build directory.

 I might wind up rm -rf ing /opt/local because at this point yes, my system
 is tainted, but this cruft you're so wary of is macports own. That's fine,
 it's not a blame game, let's keep it that way.

 Moving on.

 ```
 $ port provides /opt/local/share/cmake-3.24/Modules/FindIconv.cmake
 /opt/local/share/cmake-3.24/Modules/FindIconv.cmake is provided by: cmake
 $ sudo port uninstall cmake
 Password:

 $ ls -l /opt/local/share/cmake
 lrwxr-xr-x 1 root wheel 11 Dec 14  2022 /opt/local/share/cmake ->
 cmake-3.24/    # I would have expected this to be gone if it was provided
 by the port
 $ sudo rm /opt/local/share/cmake
 $ sudo port install cmake
 [...]
 $ ls -l /opt/local/share/cmake
 ls: cannot access '/opt/local/share/cmake': No such file or directory
 [Exit 2]
 ```

 So indeed, this is an errant symlink issue. Where did it come from? Here,
 the creation date gives us a hint:
 `Dec 14  2022`

 ```

 ```

 I update my ports once a week max, and usually once every 2 days or so.
 The symlink was created a day after
 [4580bcd8cdb](https://github.com/macports/macports-
 ports/commit/4580bcd8cdb) so maybe it's related?

 What's https://trac.macports.org/ticket/66415, could this be relevant?
