Installing python dateutil
This will install tastypie and its dependencies:
$ easy_install pip
$ pip install django-tastypie
To get only dateutil:
$ pip install python-dateutil
I am not sure if this is different on Windows, but it does not appear you are referencing an actual link (see the Reading line). Instead, try this:
easy_install python-dateutil
That will (hopefully) get the package you need. Also, see this post for what looks like a similar issue.
