[CentOS] Problem with spamassassin under CentOS-5.7

I'm getting the following warning in my logwatch, or if I restart the spamassassin service. I've tried yum-reinstalling the packages involved but that didn't help. ------------------------------- /etc/cron.daily/sa-learn:

Subroutine IO::Socket::INET6::AF_INET6 redefined at /usr/lib/perl5/5.8.8/Exporter.pm line 65. at /usr/lib/perl5/vendor_perl/5.8.8/IO/Socket/INET6.pm line 16 Subroutine Net::DNS::Resolver::Base::AF_INET6 redefined at /usr/lib/perl5/5.8.8/Exporter.pm line 65. at /usr/lib64/perl5/vendor_perl/5.8.8/x86_64-linux-thread- multi/Net/DNS/Resolver/Base.pm line 66 Learned tokens from 1 message(s) (1 message(s) examined) -------------------------------

I wonder if anyone else is getting this?
