Compiler does not import module even when its referenced

[pdeva]

I have code like this:

import React = require('react');
import ReactRouter = require('react-router');
import cbox = require('./components/commentbox')

import Route = ReactRouter.Route;

var routes = (
  <Route name="app" path="/" handler={cbox.CommentBox}>

  </Route>
);
React.render(
  <cbox.CommentBox />,
  document.getElementById('content')
);

Note that I am clearly referencing and use ReactRouter here to create the Route alias.

However, the code produced does not import react-router:

define(["require", "exports", 'react', './components/commentbox'], function (require, exports, React, cbox) {
    var Route = ReactRouter.Route;
    var routes = (React.createElement(Route, {"name": "app", "path": "/", "handler": cbox.CommentBox}));
    React.render(React.createElement(cbox.CommentBox, null), document.getElementById('content'));
});

Expected Behavior

Since ReactRouter is referenced in the code, the react-router lib should have been in the list of imports.

I'm having exactly the same problem, but importing with ES6 style and compiling to system. Note that this only occurs when importing react-router.
