SPF error in maillog

[spaceout]

Ever since I upgraded to 8.3 I've noticed this showing up in my maillog...

"Can't locate Mail/SPF/Query.pm in @INC (@INC contains: ../lib /usr/lib/perl5/site_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/site_perl/5.8.0 /usr/lib/perl5/5.8.0/i386-linux-thread-multi /usr/lib/perl5/5.8.0 /usr/lib/perl5/site_perl /usr/lib/perl5/vendor_perl/5.8.0/i386-linux-thread-multi /usr/lib/perl5/vendor_perl/5.8.0 /usr/lib/perl5/vendor_perl) at /usr/lib/perl5/site_perl/5.8.0/Mail/SpamAssassin/Plugin/SPF.pm line 272, <GEN1170> line 208."

Is this something that's required for SpamAssassin to work correctly? I don't have SPF spam protection enabled in my server wide mail preferences, so I thought it was a little odd.

Also, should I have SPF spam protection enabled? If so, what are the recommended settings (mode and rules)?
