Control: reopen -1 This isn't actually resolved. The usage of python is still unversioned (that is, the tests invoke /usr/bin/python, rather than python3, which still fails).
The tests really have no need at all to use python. Since spamassassassin is a perl project, it'd be reasonable to reimplement them in that; OTOH, since the tests are quite simple, it'd be reasonable to reimplement them in bash. Either way, the unversioned python issue is still present. I'll work on a more complete fix.
