Cannot get scikit-learn installed on OS X

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`: ``` Downloading/unpacking scikit-learn Running setup.py egg_info for package scikit-learn Warning: Assuming default configuration (scikits/learn/{setup_scikits.learn,setup}.py was not found)Warning: Assuming default configuration (sklearn/svm/tests/{setup_tests,setup}.py was not found)Appending scikits.learn configuration to Ignoring attempt to set 'name' (from '' to 'scikits.learn') Appending sklearn.check_build configuration to sklearn Ignoring attempt to set 'name' (from 'sklearn' to 'sklearn.check_build') Appending sklearn.svm.tests configuration to sklearn.svm Ignoring attempt to set 'name' (from 'sklearn.svm' to 'sklearn.svm.tests') blas_opt_info: FOUND: extra_link_args = ['-Wl,-framework', '-Wl,Accelerate'] define_macros = [('NO_ATLAS_INFO', 3)] extra_compile_args = ['-faltivec', '-I/System/Library/Frameworks/vecLib.framework/Headers'] ```
