Should be `dependency_links` (with a 'd')?

I'm not very familiar with this option, but from a brief scan of the documentation, I'm wondering:
1) Does setuptools expect this to be a list of URLs?  Right now, your list comprehension is pulling in the `hg+` prefix:
```
(Pdb) DEPENDENCY_LINKS
['hg+https://bitbucket.org/birkenfeld/pygments-main@33931e7#egg=pygments']
```

2) I'm not sure if adding a dependency link is sufficient for installing that dependency.  Will pygments need to be listed separately in the list of package requirements?
