by default, Sage will be using the system python3, sure. And gmp, flint, ntl, mpfr, arb, pari, ecl, singular, R, glpk, etc etc etc On a recent Fedora on a newish desktop building, docs included, from scratch, with all the usable system packages, takes less than an hour. > > The only way I have found to clean this up is by doing a "make distclean", > which makes for quite a heavy rebuild process!
