Buildout seems to have always just worked™ in the past, but I can't seem to get it to download my dependencies this go-around. Here's my `buildout.cfg`:

```
[buildout]
parts = python_section
develop = .
eggs = buildoutstarter
versions = versions

[versions] 

[python_section]
recipe = zc.recipe.egg
interpreter = python
eggs = ${buildout:eggs}

```

Here's my `setup.py`:

```
#!/usr/bin/env python

from setuptools import setup, find_packages

setup(
    name = "buildoutstarter",
    version = "0.1.0",
    license = "LGPL",
    packages = find_packages('src'),
    package_dir = { '': 'src'},
    install_requires = ['setuptools',
        'jinja2',
    ],
)

```

Unfortunately, running `bin/buildout` doesn't seem to download Jinja at all. In fact, running `find . -iname "*jinja*"` doesn't yield anything, so it's apparent that Buildout isn't doing anything with the package. Why isn't it downloading the package?
