[CentOS] i386 version of Perl getting installed on x64 system?

I am trying to install:

perl-Compress-Zlib
perl-Digest-Perl-MD5
perl-Net-DNS
perl-Time-HiRes
perl-Email-Valid
perl-File-ReadBackwards
perl-File-Scan-ClamAV
perl-Mail-SPF-Query
perl-libwww-perl
perl-LDAP
perl-Unix-Syslog
perl-Mail-SRS
perl-Net-CIDR-Lite
perl-Mail-SPF

which are all either noarch or x86_64 rpms yet it wants to install perl i386 version?
I could ask on rf list but it wont let me subscribe so that's of no help:/

Is there an obvious reason for this, or another bizarre erroneous dependency issue?

Thanks!
