"using below Perl script,...."

Not a script; a fragment and not one from which I can deduce what you're doing... despite the (semi-) self-explanatory message, Can't locate auto/APR/Request/Param/fh.al in @INC -- which means that somewhere, your actual code is looking for fh.al other than where it actually exists (if, indeed, it does on your machine).

You're going to need to give me (and possibly, better informed Monks, as well) more information.
