Remove distutils use

setuptools is a better documented and well maintained enhancement based on distutils. While it provides very similar functionality, it is much better able to support users on earlier Python releases, and can respond to bug reports more quickly. A number of platform-specific enhancements already exist in setuptools that have not been added to distutils, and there is been a long-standing recommendation in the distutils documentation to prefer setuptools.
