Installations error with Python 3.4 (Windows)

If I try to install iapws with the command

pip install iapws 

using Python 3.4 on Windows:

>python -V
Python 3.4.3

I get the following error message:

Collecting iapws
  Using cached iapws-1.1.1.tar.gz
    Complete output from command python setup.py egg_info:

Installing on Linux works with Python 3.4.2.

Another information: If I install it from the source, it seems to work (instead of using pip to download it from pypi):

> python setup.py sdist
> pip install dist\iapws-1.1.1.zip
Processing c:\gemeinsame dokumente\workspace\iapwspy\dist\iapws-1.1.1.zip
Requirement already satisfied (use --upgrade to upgrade): scipy in c:\opt\python34\lib\site-packages (from iapws==1.1.1)
Installing collected packages: iapws
  Running setup.py install for iapws
Successfully installed iapws-1.1.1

You are right, the version in pip don't have the last pull request from spontarelliam to solve this bug. Use the last commit in github.
