Perhaps if you give us a little information, such as which target operating systems you are concerned with, what type of application your product is and how your product installs would help us to to help you. Do all of the target systems you are trying to install your product on to have Perl installed?

Please read How do I post a question effectively? and the PerlMonks FAQ.

Update: Niel, do not over write the original question you have posted, since this now make no sense to someone reading it the first time, and existing replies can contain advice/content which now has no context. Simply mark posts as updated in a similar manner to this.

Thanks
