Stream is not defined in `inherits` call.

Hello everyone!

I got the following error on my application bootstrap (Ionic 2 RC):

inherits_browser.js:9 Uncaught TypeError: Cannot read property 'prototype' of undefined

at Object.inherits (inherits_browser.js:5)
    at _stream_writable.js:46
    at main.dev.ts:5

It seems the second argument superCtor that actually a Stream is undefined.
