Error building XRootD@v5.5.0 due to setuptools

[auras (Antonio Uras)]

Hi, the problem with the building of arrows was fixed using the procedure spotted here:

Unable to build arrow on mac

Dear people, I ran into the same issue again today, and I seemed to have solved it by running brew install llvm@14 and then I added it to my path with echo 'export PATH="/usr/local/opt/llvm@14/bin:$PATH"' >> ~/.zshrc EDIT: I actually had to remove the line from my zshrc because it then caused an issue when building ROOT. Hope it helps, Sarah
