for modules that need to be deployed across an organization, inspect and test the CPAN module carefully for conflicts. If the build file is OK, use dh-make-perl to bundle up the package for installation. Otherwise patch the make file, and then use dh-make-perl.
ya true i use lot of CPAN modules which is not listed in Debian package repository like Asterisk::Manager, etc
but I test it rigorously and third party testing also will be done on the code before getting deployed, moreover we used to give OS and the same perl(5.8.8) also with code to clients so it becomes easy.
I haven't used dh-make-perl file much, but I will try to use it henceforth.

And what will happen will not fail to happen, however much one may seek to prevent it. This is certain. The part of wisdom therefore is to stay quiet.
