If you don't have any problem with getting your setup.py code dirty use distutils.dir_util.copy_tree.
The whole problem is how to exclude files from it.
Heres some the code:

import os.path
from distutils import dir_util
from distutils import sysconfig
from distutils.core import setup

__packagename__ = 'x' 
setup(
    name = __packagename__,
    packages = [__packagename__],
)

destination_path = sysconfig.get_python_lib()
package_path = os.path.join(destination_path, __packagename__)

dir_util.copy_tree(__packagename__, package_path, update=1, preserve_mode=0)
