[Distutils] using pip to install an specific, older version

[Chris Jerdonek]

Hi, I'm trying to use pip to install an older, specific version of a
package in PyPI (specifically simplejson v2.0.9):

http://pypi.python.org/pypi/simplejson/2.0.9

I've tried a few variations of the syntax below, but it always seems
to install the newest version (v2.5.0).  I don't know if this is an
issue with simplejson, how I'm using pip, or something else.  Based on
the below, can anyone say why it's not working and how to correct the
behavior?

Thanks,
--Chris
