I cannot install scikit-learn. I can install other packages either by building them from source or through pip without a problem. For scikit-learn, I've tried cloning the project on GitHub and installing via pip without success. Can anyone please help? Here is part of my pip.log:

Install SciPy Superpack or EPD to get all the required dependencies in one shot under OSX.
