Hi there. Thanks for taking interest in JavaScript::Lint. Unfortunately, it's actually quite broken with the latest version of JavaScript.pm, and I haven't figured out why yet. I just wanted to warn, in case somebody spent time trying to package it.
If you're desperate, I also maintain jslint4java < http://code.google.com/p/jslint4java/> which has an alternative command line interface. It does rely on Java being installed however. -Dom
