I'd suggest you return your system perl to normal, and install your own perl elsewhere on the system. If you mix and match a vendor perl and modules built from cpan you can run into problems after the OS has upgraded various parts of perl. User your OS package manager reinstall perl, note that some OS split perl across numerous packages. http://perlbrew.pl/?perlbrew makes it easy to install and maintain your own perl, or multiple versions should you require it, not that the process of manually building perl is particularly difficult.
