“Without any further ado,” talk with your boss and ask him or her to arrange for you to have access to CPAN.   (You can, if necessary, install all of the modules that you need locally to just your own account and machine, so there are no system-integrity risks.)   There is zero doubt in my mind that there is really no other business-justifiable way to get this job done.   (And there undoubtedly will be more business-cases like this one.   You must have the Right Tools For The Job.)
