Title: Using setuptools instead of distutils.

When use distutils.core. You can see it:

```
/usr/lib64/python2.7/distutils/dist.py:267: UserWarning: Unknown distribution option: 'install_requires'
```

In fact, you want to install dependencies are not installed. need to be using setuptools instead of distutils.
