setup.py isn't including modules

setup.py includes modules in the same directory it is in but leaves out modules in the site.packages directory and in a lib folder I have added to the pythonpath.

Don't tell me it doesn't just import files like the python interpreter. It should if you name them.

programdir-->
programdir-->
datadir
program.py
functions.py
setup.py

setup.py

from distutils.core import setup

setup(name = "program",
    version = "1.0",
    description = "a program",
    author = "me",
    author_email = "email@email.com",
    url 开发者_运维百科= "http://www.url.com",
    py_modules = ["program", "functions", "tweepy", "anothermod", "webbrowser","" ],
    data_files  = [("data", ["data/intros.txt"])],
    long_description = """
    Descriptttttionnnn
    """
        )

What am I doing wrong?

The setup.py is responsible for bundling and installing YOUR sources, not dependencies. However, you can specify requirements with install_requires (read the manual). This will be used by pip or setuptools to install the given dependencies, but it will not bundle them either.

Julius is using distutils, not setuptools. This means that requires shall be passed to the setup() function rather than install_requires. See the docs:
