`//= require` is not working in connect-assets
===

I am using [connect-assets][1] on an express.js app running on development mode. 

 - I have `app.use(require('connect-assets')())` inside `app.config()`
 - I have `main.js` and `util.js` in `<PROJECT-ROOT>/assets/js` folder
 - In `main.js`, there is only one line: `//= require ./util`
 - In template, there is `!= js('main')`

So, the he generated html includes `<script src='/js/util.js'></script><script src='/js/main.js'></script>`. However, the request to `/js/main.js` succeed without errors but the request to `/js/util.js` failed.

Am I missing anything?
