Summary: Version 2.0.3 causes errors in subsequent pip installs 


Initial Comment:
When I install python-daemon 2.0.3 in a virtual environment with pip, an error is reported and subsequent installs using pip seem to fail with the same error:

=====

The pip.log is attached, I get the same error at the end when I install other modules (flask, celery, for example). 

Rolling back to 2.0.2 solves this issue, but wanted to report this in any case.

Using Python 2.7.6 and pip 1.5.6
