This error message indicates you to be mixing non-rpm-installed 
perl-dists (/usr/local/share/perl5) with rpm-installed perl-dists.

Likely, your non-rpm-installed perl-modules/dists originate from an 
older install (likely you upgraded Fedora) and are incompatible with 
Fedora's perl.

To avoid such surprises, my advise would be not to use any 
non-rpm-installed perl-dists.

If you cannot avoid them, you'd first have to remove all perl-modules 
under /usr/local and to rebuild/reinstall all of them.
