Yeah, I found it out at the tutorial for modules:

http://www.perlmonks.org/index.pl?node_id=260683 in 1/2 an hour of reading...

First of all, I could install all the modules at another directory outside of my Apache 2 (WAMPP) distro and add the path with a 'use lib my/path/' Perl script statement when it is required before the use module.

That would do for my case.

Besides, there is a module called ExtUtils::Installed that can take care of some of these tasks of supervising the modules that should be installed or that might be uninstalled (for some reason).

These covered all my doubts with new blessings (and I am not thinking of objects :))

Thanks a lot for 'your misterious ways of' solving my doubts.
