Comment (by andlabs):

 It now passes the download, but fails to build on Xcode 9.2 because it now
 requires C++17 (use of <optional>). That's a separate issue though; thanks
 in the meantime!

 (I did try manually patching the Portfile to fix this, but kept running
 into linker errors with the MacPorts clang-14, with and without macports-
 libstdc++; either the typeinfo for std::bad_optional_value is missing or
 some operator<<(ostream) overloads were missing. I don't actually need
 kicad right now, and I'm sure my MacPorts setup is supremely broken in
 other ways, so maybe all this is me. So while I can't get it work I'm sure
 the CI shows it's working.)
