Just to add to the other good responses here already: It also depends on what versions of Perl you test your script / application against. If you've designed your code to be very portable, then you don't need to worry too much about the environment you're running it in, except that it might need to meet a few minimum requirements (in your case, Mojolicious being installed would probably be the most important). When a new version of Perl is released, distros won't pick it up immediately, so you have some time to test your program against the new Perl version.

(If your program isn't designed to be particularly portable, the bundling suggestion and the other monks' comments apply.)
