the man page for pkg_rr asks that people not report "some make replace
that pkg_rr did failed" as a pkg_rr problem, because it's not really
true but mostly because the subset of peopel that don't like pkg_rr then
ignore your report, whereas some of them could perhaps be helpful if it
is properly reported as a simpler failure.

Yes, the basic issue is that new scons3 dropped support for py3, and the
basic solution is to upgrade to 4, but we don't really have support for
that, and 99% people only have scons as a build tool (because somebody
else wrongly thought it was better than autoconf 5 years ago :-).

You can still do it and continue.   Unless you actually *want* scons3,
removing it is best.  The tools that are needed for other things will
get built.
