I'm pretty sure that Homebrew does not have exactly the same set of software that MacPorts does, so it seems likely that we still have some ports that would be affected by this that have not already been fixed by Homebrew's efforts.

My other concern specific to Xcode 10 on macOS 10.13 is whether this would remove the ability to build i386 software, which is something I want to retain.
