Can I recommend converting /src/SpahQL.js to require() all of the other js files Node.js-style, then use node-browserify to merge them together and strip the require()s back out, and then use UglifyJS to minify the resulting file? I suggest this because you already require nodeunit for tests so Node.js is needed, and make, rake, and bundle are all superfluous to this Javascript-based project (and not every JS dev is familiar with the Ruby build tools).
From David:
I agree.
