there is nothing evil or risky in the system perl IF you use it as intended by the system

Yes, I can see how that could be convenient for an individual working alone or in a small team (such as the OP in this thread!) ... especially for modules with complex third-party dependencies.

As indicated here, I have been scarred by previous experiences of having to support products (which contain Perl scripts) that run on thousands of different customer machines. In such an environment, the last thing you want is to be swamped by support calls from angry customers who made a "harmless" upgrade to their OS ... which just happened to upgrade their system Perl to a version that breaks the Perl scripts included in your product.
