I tried again (in a fresh shell, after make distclean, ./bootstrap, source 
.homebrew_build_env) with 
https://github.com/sagemath/sage/pull/39571 
and since it fails to compile ipykernel, I tried in addition:
./configure --enable-system-site-packages --disable-notebook

It's still trying to build ipykernel, and it fails to compile it with

[ipykernel-6.27.1] [spkg-install] ModuleNotFoundError: No module named 
'jupyter_core'

Not a lucky trial.

A side question:
looking at ./configure --help, I saw option --enable-modular_decomposition. 
which concerns an experimental package that we don't use anymore (it was 
buggy).
If I want to make it disappear, is it sufficient to remove directory 
build/pkgs/modular_decomposition ?

Thanks,
David.
