in reply to When to bundle Perl with your app?

I consider my target Perl version and installed modules part of my application, just to avoid the 'vendor changed perl installation' issue. OTOH, this is an internal system, and my application does not need to run on everything out there. That being said, on platforms like Win32, where perl does not come bundled, bundling Perl with your application removes a layer that the user needs to manage.
