make bootstrap-clean distclean did not solve the problem. I have
considered removing python3 from my system and reinstalling it but there
are so many other things I have that depend on python3 and would be
removed. I don't want to have to reinstall such a huge list. I am not
sure what to do next. One thought is to delete my entire sage directory
and pull it afresh but I am not sure this will address the issue that blas
is not being found properly.
