Installed spamassassin from the atomic testing repo, seems fine so far.
DCC/Pyzor now require paths to be entered in spamassassin local.cf;
There are some compatibility issues with /usr/bin/pyzor that requires a (less than ideal) -Wignore::DeprecationWarning to be added after the shebang to avoid:
/usr/lib/python2.6/site-packages/pyzor/__init__.py:11: DeprecationWarning: the sha module is deprecated; use the hashlib module instead
/usr/lib/python2.6/site-packages/pyzor/client.py:12: DeprecationWarning: the multifile module has been deprecated since Python 2.5
/usr/lib/python2.6/site-packages/pyzor/__init__.py:429: DeprecationWarning: object.__init__() takes no parameters
