Totally agreed. Bundler is finally the solution to some of the RubyGem failings over the years. RubyGems has been friggin awesome, and one of the best best aspects of the Ruby environment, however the dependency management was not its strong suit and the fact that it declares dependencies one at a time means it might be impossible to fix with RubyGems itself.
Bundler is an amazing solution to this, and the fact that it works within RubyGems (via "gem bundle" command) should make this the ubiquitous solution to deploying apps for the future.
Also should plug the fact that the wycats/clerche duo has been working on this problem for a while. Their last major success with it was with the thor bundler with Merb, which was been working well for me over the last 9 months (I've now switched to the new bundler).
Bundler is meant for gem dependency management. Jeweler is meant for another problem entirely, creating gems from scratch and packaging/releasing them (hopefully to http://gemcutter.org).
