MythTV Install Error

I'm installing MythTV on a new CentOS 6 frontend-only host with a:

yum install mythtv --enablerepo=atrpms\*

command and am getting the following error:


Transaction Check Error:
   file /usr/share/man/man3/XML::SAX::Base.3pm.gz conflicts between 
attempted installs of perl-XML-SAX-Base-1.04-3.el6.noarch and 
perl-XML-SAX-0.96-7.el6.noarch
   file /usr/share/man/man3/XML::SAX::Exception.3pm.gz conflicts between 
attempted installs of perl-XML-SAX-Base-1.04-3.el6.noarch and 
perl-XML-SAX-0.96-7.el6.noarch


I've tried manually installing the two packages mentioned separately and 
they're definitely colliding.

Any thoughts on how to get around this?

Thanks.
