The third edition came out recently and it's been the best written book on learning Ruby that I've read. It's a bit beyond beginner-stage learning, but if you have some programming under your belt you might light the thorough approach. (The first chapter has you digging into the ruby core to learn the standard library.)
It's very well-written and I think it's the best way to learn.
