I wonder if it's possible for llamafile to distribute without the need for Xcode Command Line Tools, but perhaps it's necessary for the single cross-platform binary.

Loved llamafile and used it to build the first version of https://recurse.chat/, but live compilation using XCode Command Line Tool is a no-go for Mac App Store builds (runs in Mac App Sandbox). llama.cpp doesn't need compiling on user's machine fwiw.
