[CentOS] best repo for perl-IO-Zlib perl-Archive-Tar

With all due respect to the various people, their hard work and associated
repos, where is the best place to do a yum install for these two packages
below in regards to an internet facing production Centos 4.4 server

perl-IO-Zlib    
perl-Archive-Tar

I noticed dag and karan repos appear to have it and my experience and
research tells me that using CPAN is not an option for possible problems at
times (no disrespect intended)

background: spamassassin and sa-update

sa-update complains about Can't locate Archive/Tar.pm in @INC etc etc blah 

research showed that it *appears* they are in fedora core "core" yet
evidentally not in the upstream "core"???

thanks and kind regards,
