I'm not sure about deployment but the 'hello world' is essentially part of the environment:

You create a new image and then start piecing things together from there. GNU Smalltalk is probably what you want if you want to stick to the CLI. That said, it's not exactly a representative example when you want the same program that prints to stdout or something.

I'm curious to know about this aspect of it because my first step after the hello world is usually to figure out how to host the thing.
