Doing multiple almond builds with a nodejs script, example

build.js

//Download jquery.js and place it in the build, do not use require-jquery.js 
//in the build, since each of the build layers just needs almond and not the 
//full require.js file.
//This file is run in nodejs to do the build: node build.js

//Load the requirejs optimizer
var requirejs = require('./r.js');

//Set up basic config, include config that is
//common to all the requirejs.optimize() calls.
var baseConfig = {
    baseUrl: "some/path",
    locale: "en-us",
//  optimize: "uglify",
    optimize: "none", // For debugging built versions

    wrap: true,
    paths: {
        //Remember, use downloaded jQuery 1.7 or greater,
        //not require-jquery.js
        'jquery': 'libs/jquery/jquery',
        'underscore': 'libs/underscore/underscore',
        'backbone': 'libs/backbone/backbone',
        'templates': '../oerglue_templates'
    },
    
    //All the built layers will use almond.
    name: 'almond'
 };

//Create an array of build configs, the baseConfig will
//be mixed in to each one of these below. Since each one needs to
//stand on their own, they all include jquery and the noConflict.js file

var configs = [
    {
        include: ['jquery', 'noConflict', 'main'],
        out: '../oerglue_js_min/main.js'
    },
    {
        include: ['jquery', 'noConflict', 'main-frame'],
        out: '../oerglue_js_min/main-frame.js'
    },
    {
        include: ['jquery', 'noConflict', 'main-mods'],
        out: '../oerglue_js_min/main-mods.js'
    },
    {
        include: ['jquery', 'noConflict', 'main-edit'],
        out: '../oerglue_js_min/main-edit.js'
    }
]; 


// Function used to mix in baseConfig to a new config target
function mix(target) {
    for (var prop in baseConfig) {
        if (baseConfig.hasOwnProperty(prop)) {
            target[prop] = baseConfig[prop];
        }
    }
    return target;
}

//Create a runner that will run a separate build for each item
//in the configs array. Thanks to @jwhitley for this cleverness
var runner = configs.reduceRight(function(prev, currentConfig) {
  return function (buildReportText) { 
    console.log(buildReportText);
    requirejs.optimize(mix(currentConfig), prev);
  };
}, function(buildReportText) {
    console.log(buildReportText);
});

//Run the builds
runner();

noConflict.js

jQuery.noConflict(true);

This is based on this gist, and part of this requirejs thread.

I had to add baseUrl to basConfig or node would complain:
baseUrl: "public/oerglue_js",

Then I changed the paths to match my system and it works great!

Thanks for the catch, i added baseUrl to the gist and also console.log() for the build output
