title: pip can't find latest versions of a pypi project
body: <p>I'm trying to install <a href="http://pypi.python.org/pypi/django-crowdsourcing/1.1.21" rel="noreferrer">http://pypi.python.org/pypi/django-crowdsourcing/1.1.21</a> using pip. I'm getting</p>
  
  <pre><code>$ pip install django-crowdsourcing==1.1.21

    Could not find a version that satisfies the requirement django-crowdsourcing==1.1.21 (from versions: )
  No distributions matching the version for django-crowdsourcing==1.1.21

  <p>If I try an upgrade, it only finds version 1.1.19.</p>
  
  <pre><code>$ pip install -v --upgrade django-crowdsourcing
  Downloading/unpacking django-crowdsourcing
    Using version 1.1.19 (newest of versions: 1.1.19, 1.1.18, 1.1.17, 1.1.16, 1.1.15, 1.1.14, 1.1.13, 1.1.12, 1.1.11, 1.1.10, 1.1.9, 1.1.8, 1.1.7, 1.1.6)

  <p>It looks like django-crowdsourcing version 1.1.21 has some good tags</p>
  
  <pre><code>$ hg tags
  tip                              289:8796aae85e34
  1.1.21                           288:2f39596495a7
  1.1.20                           281:fe00699aa3ff

  <p>and the correct version number in setup.py</p>
  
  <pre><code>try:
      from setuptools import setup

  <p>PyPi clearly knows about version 1.1.21 since that's what comes up when you go to <a href="http://pypi.python.org/pypi/django-crowdsourcing/" rel="noreferrer">http://pypi.python.org/pypi/django-crowdsourcing/</a> Why does pip think version 1.1.19 is the latest version?</p>
  
  <p><strong>Edit</strong></p>
  
  <p>Sheepishly, I forgot to point out I'm the maintainer. @Matthew Schinckel is right. Here are the two commands I needed, which I found out from a tutorial I didn't see before: <a href="http://wiki.python.org/moin/Distutils/Tutorial" rel="noreferrer">http://wiki.python.org/moin/Distutils/Tutorial</a></p>
  
  <pre><code>$ python setup.py register
  $ python setup.py sdist upload
