Can't install PIL after Mac OS X 10.9

Following worked for me:

ln -s  /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/Tk.framework/Versions/8.5/Headers/X11 /usr/local/include/X11
sudo pip install pil

UPDATE:

But there is more correct solution below, provided by Will.

open your terminal and execute: xcode-select --install

open your terminal and execute:

xcode-select --install

sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/System/Library/Frameworks/Tk.framework/Versions/8.5/Headers/X11/ /usr/local/include/X11

helps for me! os x 10.9

pip install pillow

but! after pip install ...

*** ZLIB (PNG/ZIP) support not available

and finally i fix it by running:

xcode-select --install

then reinstall pillow

pip install pillow
