in reply to How to deliver a perl application to a client?

Best you spin up a system or VM, try to match the target system as close as you can, same OS, same perl version etc. As far as delivering your app goes, perhaps you could package it using pp or similar, or instruct them on installing cpanm using their OS package manager, and provide a cpanfile listing your apps perl dependencies (a quick start guide here). If you describe the situation in more detail perhaps it'd help to guide you better.
