So I have wiped the faulty libraries, make check the older versions and only install if pass; but the stage compare still fails between 2 and 3 with just plain "make" (attached). I am currently retrying with make bootstrap4-lean - I know I have finished 4.6.1 correctly *once*, I just don't know how :-(.
