Market Data example fails

[cryptal]

Running node v0.10.4 and microtime 0.3.3. Checked out the code.

$ npm examples/market_data.js

~/trader.nodejs/lib/books/mtgox_rest.js:45
    maybe_update(0, bid, book.bids[book.bids.length - 1]);
                                            ^
TypeError: Cannot read property 'length' of undefined

Same error here.
I solved It by replacing mtgox.com by data.mtgox.com on "./trader.nodejs/examples/market_data.js:39" market_data.js around line 39 (i added some lines). That's the "host" property

original:
35 var gox = books.build({
36 exchange: 'mtgox',
37 depth: 'L1',
38 protocol: 'rest',
39 host: 'mtgox.com',
40 // specified per mtgox api v0
41 product: 'EUR',
42 });

replaced:
35 var gox = books.build({
36 exchange: 'mtgox',
37 depth: 'L1',
38 protocol: 'rest',
39 host: 'data.mtgox.com',
40 // specified per mtgox api v0
41 product: 'EUR',
42 });
