Got an answer:

The problem is that the module search behavior changed from 5.16 (F19) 
to 5.18 (F20).  Now perl will stop looking for modules if any prior 
folder is not allowed. Before PERL5LIB extended @INC.  Now if it 
includes /root. for instance, any module search by a non-root user will 
fail. Each non-root user needs to have PERL5LIB referring only to 
folders where it has read permission.

Whew. Figured this out with the great assistance of the Perl Monks.
