feature.pm is distributed with Perl already. Copying a different feature.pm that did not come with your Perl into the Perl directory will likely not work, or maybe even break your existing Perl installation. Don't do that.

Also, the error you posted seems quite unrelated to that. You don't even show the script that produces this error.

It seems to me that you have messed up your Perl installation quite badly, as Exporter.pm seems to be broken. The best advice I can give is to restore from backup, or if you don't have working backups, to delete and reinstall Perl.
