On OS X 15.6.1 and many homebrew packages, if I take a fresh git clone and 
run `./bootstrap` and `./configure` with the flags 

   -   `--disable-editable` (to avoid 
   https://github.com/sagemath/sage/issues/40869)
   -   `--with-system-singular=no` (to avoid 
   https://github.com/sagemath/sage/issues/40873)
   -   `--with-python=python3.13` (so that Sage doesn't use "python3" which 
   is Python 3.14 on this machine)

I get one failure:
