[Skunkworks] Perl

Does anyone know how to change the code for a perl module that has already been installed? i.e. without uninstalling, modifying and installing again? -- Thanks and Regards, Erick Njenga Nyachwaya, M: +254-725-008-790 <http://www.facebook.com/ErickNjenga> <http://www.twitter.com/ErickNjenga>
