You'll need to look at the licenses for each library/module you use,
and be sure to comply with their respective licensing terms.

If you package your game to include Ruby itself, then for that you'll
need to follow its licensing terms
(http://www.ruby-lang.org/en/LICENSE.txt) for its files.

Right. Different libs that you use (say, RubyGame, SDL, etc.) may have
licensing terms different to that of Ruby itself, so if you distribute
those libs with your game, you'll need to abide by their terms
(respectively -- possibly different terms for each library).

The licensing info for a given bit of software is usually in the top
level of the source directory in a file called "COPYING", or maybe
license.txt or something similar.

No experience with that.
