Eh, the OP wants to install a module. He doesn't want to upgrade or modify his perl. It shouldn't be necessary to upgrade or modify perl past 5.10 to install the module the OP needs.

So what the OS uses perl for a lot of administrative work? Even if it is doing it inbold face? It doesn't matter. It's irrelevant for what the OP needs. There's no need to spread FUD.

You will find that if you update perl via CPAN or CPANPLUS that some of the desired updates are actually dependent on v10.0.1.

Yes. How's that relevant to installing a module? Why not respond to a question how to install a module with "be careful when upgrading your libc"? After all, libc is used by a lot of tools as well.
