Building gruvi from a clean git clone will fail on the first attempt

[jmooreoliva]

Building gruvi ("python setup.py build") from a clean git clone will fail on the first attempt. After the error occurs, running "python.setup.py build" again will succeed.

System issue observed on:

python 3.4.1 windows 32 bit
Visual studio 2010 express for compilation
git cloned on 2014-06-21 12:00 PM (I am new to git, not sure if there is a revision number as in svn to refer to instead)

Steps to reproduce:

a) git clone https://github.com/geertj/gruvi
b) cd gruvi
(if dependencies are not installed, run pip install -r requirements.txt)
c) python setup.py build

The following is the output of the build process until it fails
