Mac OS Sierra virtualenv (python 2.7) pip установить ошибку mysqlclient

в Mac OS Sierra создан virtualenv с использованием python2.7 и пытается установить mysqlclient для использования Django w / MySQL. Я установил MySQL 5.6 через homebrew. Запуск "pip install mysqlclient" дает эти ошибки:

Running setup.py bdist_wheel for mysqlclient ... error

любая помощь была бы весьма признательна.
