Example of working jQuery/Gumby Framework with Require.js, after replacing define(window.Gumby) with define('Gumby') in gumby.min.js

app.js

/*global define */
define(['jquery','gumby'], function () {
    'use strict';
    console.log('jQuery ' + $().jquery); // jQuery 1.9.1
    console.log('Gumby is ready to go...', Gumby.debug()); //Gumby is ready to go... Object { $dom={...}, isOldie=false, uiModules={...}, more...}
});

main.js

require.config({
    paths: {
        'jquery': '../components/jquery/jquery', //Local jQuery
        'gumby': '../components/gumby/js/libs/gumby.min'
    },
    shim: {
        'gumby': {
            deps: ['jquery'] //Shim to ensure jquery is loaded first
        }
    }
});

require(['jquery','app'], function ($, app) {
    'use strict';
});
