Django Pillow/PIL error

Question

I'm trying to do the Tango with Django tutorial, which uses django 1.5. I'm using virtualenvwrapper. I installed Pillow with pip.

$ pip freeze
Django==1.5.5 
Pillow==2.4.0 
South==0.8.4 
wsgiref==0.1.2. 

(tangowithdjango)~/dev_django_projects/tangowithdjango$ which python
 /Users/7stud/.virtualenvs/tangowithdjango/bin/python
(tangowithdjango)~/dev_django_projects/tangowithdjango$ python --version
Python 2.7.6

However, in chapter 8 I get the following error:

(tangowithdjango)~/dev_django_projects/tangowithdjango$ ./manage.py syncdb 

CommandError: One or more models did not validate: rango.userprofile: "picture": To use ImageFields, you need to install the Python Imaging Library...

I am unable to install PIL, which is why I installed Pillow:

(tangowithdjango)~/dev_django_projects/tangowithdjango$ pip install PIL
Downloading/unpacking PIL
  Could not find any downloads that satisfy the requirement PIL
  Some externally hosted files were ignored (use --allow-external PIL to allow).
Cleaning up...
No distributions at all found for PIL
Storing debug log for failure in /Users/7stud/.pip/pip.log

When I try:

$ pip install Pillow-PIL 

which is supposed to convert buggy import statements into good import statements, I get the error:

Could not find a version that satisfies the requirement Pillow-PIL (from versions: 0.1dev)

Finally, if I try to use PIL in the shell:

(tangowithdjango)~/dev_django_projects/tangowithdjango$ ./manage.py shell
