Cannot install Scrapy 0.18 on Mac OS 10.8.4 running Python 3.3

Question

I have installed both pip and easy_install on my MacBook Pro running Mac OS 10.8.4 and Python 3.3. When I try and use pip to install Scrapy (http://scrapy.org/), I receive the error message shown at the bottom. I receive a similar error message with easy_install. I initially assumed that something was wrong with the Scrapy installation process specifically but it appears that I am unable to install any Python packages. I just installed Python today so I have not successfully installed any Python packages ever on this machine. Any help would be greatly appreciated.

The document at http://doc.scrapy.org/en/0.18/intro/install.html states scrapy requires 2.6 or 2.7. I can't find anything saying it can run with a later version of python. You might want to try installing python 2.7 in addition to 3.3, then using virualenv to run scrapy.
