This is why it's recommended to install a separate "application" copy of perl separate from the OS' version that you control separately from whatever vagaries yum or dpkg or port or whathaveyou try to inflict upon you. Disk is cheap and the minimal amount of time it takes is repaid manyfold in the flexibility and insulation from external changes you gain.
