The end of the output of configure is this seeming contradictory info:

configure: notice: the following SPKGs did not find equivalent system
packages: brial cbc cddlib cliquer coxeter3 eclib ecm fflas_ffpack flintqs
fplll gf2x gfan givaro glpk gp2c gsl iconv iml lcalc libatomic_ops
libbraiding libsemigroups lrcalc m4ri m4rie nauty ninja_build openblas palp

pari_seadata pari_seadata_small pcre perl_cpan_polymake_prereq
perl_term_readline_gnu planarity ppl python3 r rw suitesparse symmetrica
sympow tachyon yasm zeromq zn_poly

checking for the package system in use... unknown

wdj@jeeves sage-9.2.beta9 % which python3

/usr/local/bin/python3

wdj@jeeves sage-9.2.beta9 % python3 --version
Python 3.7.9

There isn't a python3 system package but there is?
