When I try to install the Cryptography package for Python through either pip install cryptography or by downloading the package from their site and running python setup.py, I get the following error:

I found other egg_info error posts (here and here) but the solutions there provided wouldn"t solve my problem. Also, I am able to install other packages through PIP.

PIP version 1.5.4 setuptools version 2.2
