--------------------+--------------------
 i have some outdated ports, like clamav, but i cannot upgrade due to cmake
 errors, so i tried to install cmake manually, with/without +docs, with
 +python38/python39.

 other macs running the same 10.13.6 don't have this problem.

 {{{
 port clean --all cmake; port -dv install cmake +docs -python38 +python39
 }}}
