Although I more or less accept your argument that we need to be bolder in evolving Perl 5, I think you've contradicted yourself a little bit.
You're trying to give examples that are real world, but in the real world (at least in Java and Perl), pretty much all code is going to need to rely on third party libraries, so you need some sort of dependency management system. Both Perl and Java have massive codebases to draw from, much of it open source.
So a real Java programmer is going to write classes, but they're probably also going to compose their app using Spring. Which means they either need to hack an Ant script, or configure a Maven project. Neither of which is trivial (well, configuring a basic Maven project is trivial, but trying to do anything outside the One True Maven Way is not).
The fact that so much of the Java world depends on Spring, and that most of the apps written using Java these days wouldn't be sane without it doesn't seem to bother the Java community. Why are some people so bothered that modern Perl apps need to depend on Moose (or some other framework, e.g. Catalyst, DBIx::Class, or what have you)?
