Why doesn't nose see my plugin?

[Roy Smith]

I'm attempting to write a nose plugin.  Nosetests (version 1.3.0) is not 
seeing it.  I'm running python 2.7.3.  The plugin itself is:

mongo_reporter.py:
------------------------------------------------
import nose.plugins
import logging

log = logging.getLogger('nose.plugins.mongoreporter')

class MongoReporter(nose.plugins.Plugin):
    name = "Mongo Reporter"
    
    def options(self, parser, env):
        super(MongoReporter, self).options(parser, env=env)

    def configure(self, options, conf):
        super(MongoReporter, self).options(options, conf)

    def finalize(self, result):
        log.info("Hello from Mongo Reporter")
------------------------------------------------

I also have setup.py:

------------------------------------------------
#!/usr/bin/env python

from setuptools import setup, find_packages

setup(
    name = "Mongo Reporter",
    version = "0.0",
    entry_points = {
        'nose.plugins.1.10': ['mongoreporter = 
mongo_reporter.MongoReporter'],
        },
    )
------------------------------------------------

I'm not really familiar with setuptools, so I don't know if I've got a 
"I'm doing something with nose" issue or a "I'm doing something wrong 
with setuptools" issue.
