rails: bundle error on El Capitan

rails_bundle_erorr_elcapitan.txt

If..
bundle install will not work with if you because you recently updated to El Capitan 10.10
Your error message will look like this: 
ERROR: "bundle install" was called with arguments ["json-1.8.3"] or this:
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
To get around this issue try:

$xcode-select --install
$sudo chown -R (whoami):admin /usr/local
$sudo xcode-select --reset
$softwareupdate --install
$sudo xcodebuild -license
