the Python you're using is built with Tkinter, and PIL's setup.py script 
thought that it had found proper header files, but the compiler couldn't 
find them.  since you won't need the Tk stuff for your web application, 
the easiest way to fix this is to trick the setup.py script into 
ignoring the Tkinter extension.

look for this section in the setup.py file:

try:
     import _tkinter
except ImportError:
     _tkinter = None

and change it to

try:
     import _tkinter_is_not_important
except ImportError:
     _tkinter = None

(or something similar; the important thing here is to make sure that the 
_tkinter variable is set to None)
