Smol update. I updated the whole system (portsnap update, portmaster -Rafd)
and after getting through a few update quirks (DEFAULT_VERSIONS+=ssl=openssl
warning is no longer optional...), everything is working. This updates:
spamassassin-3.4.1_11
perl5-5.24.3
among others. And which brought me back to this:
Use of uninitialized value $msgscore in addition (+) at
/usr/local/lib/perl5/site_perl/Mail/SpamAssassin/Plugin/TxRep.pm line 1415.
Use of uninitialized value $msgscore in subtraction (-) at
/usr/local/lib/perl5/site_perl/Mail/SpamAssassin/Plugin/TxRep.pm line 1415.
which this version fixes
https://svn.apache.org/viewvc/spamassassin/trunk/lib/Mail/SpamAssassin/Plugin/TxRep.pm?view=markup&pathrev=1720440
but which hasn't been rolled into the port yet.
Perhaps because it is really slow? I'll try to do some timing experiments with
the installed version vs. the rev 1720440 version tomorrow (2:49 am my time
now).
