Yes, we could provide copies of bash, python, make and clang ourselves<br class="">
and use them instead. So far, we have always relied on Apple's toolchain<br class="">
but you're right that we don't really have to.<br class="">
<br class="">
However, remember that it's not just 3-4 binaries we're talking about<br class="">
here. Lots and lots of smaller tools would also be needed, such as ar,<br class="">
as, arch, awk, base64, bc, bison, bzip2, chgrp, chown, cpio, curl, diff,<br class="">
du, grep, fmt, gzip, ...<br class="">
<br class="">
We're currently re-using some of those from /usr/bin to reduce the<br class="">
footprint of our build dependencies. MacPorts is already being<br class="">
criticized for using too much storage and "downloading the internet"<br class="">
before installing what you initially requested, and a change such as<br class="">
this would make things even worse.<br class="">
