MimeDefang/Spamassassin failures after portupgrade

[Jim Hatfield]

I decided to update one of our mail gateways.
After portupgrading all the Perl modules which are installed
as dependencies of MimeDefang and/or SpamAssassin, I shut down
and started the daemons, and got this in the mail log:

>Jun 17 16:27:05 highland mimedefang[69165]: Multiplexor alive - entering main loop
>Jun 17 16:27:08 highland mimedefang-multiplexor[69152]: Starting slave 1 (pid 69167) (2 running): Bringing slaves up to minSlaves (2)

p5-Net-DNS was one of the modules I updated.

Will this go away if I continue and update MimeDefang? Or do I
need to fix it first?
