Hmm, OK, prioritze CentOS repo over RepoForge then will yum update
figure out the rest?  I don't see any priority settings in my yum conf files...
I'll have to read up on that.

Interestingly, I get this:

rpm -q --whatrequires perl-IO-Socket-INET6
no package requires perl-IO-Socket-INET6

However, 

yum remove perl-IO-Socket-INET6
