Correction: May not fail on *every* requires

Does fail on 'require(List::Util)'

--- Comment #2 from Petr Pisar <ppisar(a)redhat.com&gt; ---
I guess you mix XS modules compiled for old new new perl after upgrading your
Fedora. For example you installed Encode from CPAN and you try to load Encode
module compiled against perl 5.18 to with perl 5.20. Please note that perl
releases between major versions are not guaranteed to be ABI-compatible. Is
that your case?

Working with Petr, we determined the issue in my case was installing CPAN
modules in a prior version.  The workaround that resolved the issue was to
remove the contents of /usr/local/share/perl5 and /usr/local/lib64/perl5.
