Unable to install packages on OSX 10.10 with Xcode 6.1

[cburmeister]

I am unable to install Pillow and some other packages using pip.

~ → python --version
Python 2.7.5
~ → pip --version
pip 1.5.6 from /Users/cburmeister/.pyenv/versions/2.7.5/lib/python2.7/site-packages (python 2.7)

Here is a snippet from the log:

I've tried lots of suggestions from what i've been able to find on the web, this is the most similar to my issue that I can find: https://github.com/OpenBazaar/OpenBazaar/issues/370

Can anyone explain why pip is expecting an .exe here?

I have the same problem. When I tried to remove python3 and reinstall I've gotten the following error

Exception:
