Having a separate perl seems a lot easier to me than examining every new script you put on the machine to make sure it's going to work with your legacy perl.
Sure ... if you're even allowed to install a new perl on the machine. Often political or social concerns override the obvious technical solutions. Especially when "legacy systems" are concerned.
