easy_install PIL fails

I am trying to setup a dev environment on a new laptop, I am trying sudo eas开发者_C百科y_install PIL after seting up setuptools and python etc, I get this error. Setup script exited with error: command 'gcc' failed with exit status 1

I have gcc and build_essentials installed, on Ubuntu Karmic. Full traceback is at http://dpaste.de/fHiW/

You must install the python-dev package which includes the CPython header files needed to compile C extensions.
