This example does not work out of the box

It is impossible to find a solution on google or stackoverflow
Im using ubuntu-12.04.4-desktop-amd64.iso
python 2.7.3(default, Feb 27 2014, 19:58:35)
Scrapy 0.22.2

Im getting:
ImportError: cannot import name Selector
I have tried HtmlXPathSelector
ImportError: cannot import name HtmlXPathSelector
