http://gist.github.com/278801 - updates vendor/rails and then bundles gems (requires rvm) run it from rails_root, but leave it in bin/update.rb
If you're bundling rails, and not wanting to test mysql or postgresql, then run gem bundle --only default
- it will skip mysql and postgres
if you're having troubles with bundler, nuke vendor/gems and then run it again.
if you're still having issues with gem bundler, take a look at http://pastie.org/780347 - a fix is on its way (trouble with spaces in the path)
if you hit "undefined method 'gems' for #Array:..." when using bundler, just update it.
if you get a loaderror to do with 'rails/all' use --dev with the rails command
