how to install PIL on mac os x 10.7.2 Lion

I'm trying to install the latest version of PIL (1.1.7) on Mac OS X Lion (10.7.4). I generally just use PIP and the following command:

sudo pip install package_name

However, I'm getting an error message for PIL, as it is refusing to cooperate with me.

Here is what I received:

Any advice would be appreciated! Thank you!

I should also note that when trying to install Pillow as an alternative I received the exact same error message.

Have you tried using [Pillow](http://pypi.python.org/pypi/Pillow)? It's designed to be much friendlier-to-install than PIL. — kojiro, Jul 25 '12 at 20:24

@Sean I saw that thread earlier, but seeing as we face different errors, and that I am using pip, I felt a separate question may be in order. If a separate question was not in order, I apologize. Thanks you! — mcbaby, Jul 25 '12 at 20:54
@kojiro I'll definitely check it out, thanks! Interestingly enough, I received the exact same error while trying to install Pillow. Any thoughts? — mcbaby, Jul 25 '12 at 20:54
You *NEED* xcode, or at least to install the GCC without XCODE package. Without it you don't have a compiler and can't build anything that needs one. — jdi, Jul 25 '12 at 21:02
awesome, if I have xcode installed (which I do, though I never use it) what should I be doing? — mcbaby, Jul 25 '12 at 21:10
