requiring node core modules fails

This

var http = require('http')

gives

Bundling error: 

---FLAGRANT SYSTEM ERROR---

--- error #0: ---


(logs uuid: 0daef330-c86c-11e4-9de9-59ad9188bc13 )

Error: "spawn ENOENT"

code: ENOENT
errno: ENOENT
syscall: spawn
dirPath: /tmp/http115212-24815-1xspa4h


------

This is probably an issue with the package, and not browserify-cdn itself.

and this

var events = require('events')

gives

Bundling error: 

---FLAGRANT SYSTEM ERROR---

--- error #0: ---

Start by reproducing the failures for require('http') and require('events') and trace the bundling path that reports spawn ENOENT. Check what handling exists for Node core modules; done means both examples bundle without the reported error.
