Autodep
still need numpy for setup, but at least we get the right version of `python-dateutil`

`install_requires` is invalid with regular distutils. Is there a way to check if pip/distribute is in use?
 Sorry for the delay here!

As with usual in packaging, there are a million solutions :)  
- turn it off, and let people figure this stuff out themselves.  Something like "if there is no setuptools, then tell them eveyrthing they need to get going"
- just require one of `setuptools` or `distribute`.  It think this is the case for most people.  

Look for some inbound code... I think this is an improvement...
