Retried a couple of times and same result.

I thought it maybe a network related issue, so I tried running the git
command to temp directory and it completed without error, so I copied
/tmp/git/clutter to ~/gnome-shell/source/clutter. That seems to have
fixed the issue, but what caused it?

Then a little further along I get another error while building
gnome-control-center.

Making all in background
