The artistic license under which perl is distributed states quite clearly "You may otherwise modify your copy of this Package ..." (and goes on to specify some conditions that apply if you *do* modify the source).
In view of that, why on earth would you then use a perl that has been built by someone else for the purpose of helping to run an operating system - and, furthermore, expect it to serve your *own* purposes !! He gets no sympathy from me, unless RedHat have failed to adhere to the conditions of the license under which perl is distributed.
