Today I ran into this error:
Base class package “Tree::DAG_Node” is empty.
(Perhaps you need to ‘use’ the module which defines that package first.)
at /usr/lib/perl5/vendor_perl/5.8.8/XML/Validator/Schema/Node.pm line 2
An odd error from perl’s XML Validation libraries; here is how you fix it: install the Tree::DAG_Node package
yum -y install perl-DAG_Node
