Well, what I have is very common among Catalina users (see https://apple.stackexchange.com/questions/372032/usr-include-missing-on-macos-catalina-with-xcode-11, where it's advised to put `export CPATH=`xcrun --show-sdk-path`/usr/include` in your .zshprofile/.zshrc file, which is exactly what I was doing.
So I don't know if I would call it a bug, but putting some kind of message somewhere for Catalina users about this might be a good idea.
