Summary
This guide outlines my steps to install/setup Grails 2.3.7 into OS X 10.9(Mavericks).Step 1 - Install GVM
GVM(http://gvmtool.net) is a very helpful toolkit to manage the various versions of grails(groovy, gradle and etc) under Unix-like environments. So just use it if you need to work with grails over long time.
$ curl -s get.gvmtool.net | bash
Step 2 - Install Grails
It is very easy to install Grails once GVM is available.
grvm install grails
