Как установить MySQLdb на Mountain Lion

Я новичок в Python, и у меня возникли проблемы со сборкой MySQLdb при попытке запустить Google AppEngine SDK. Я только что обновился со Snow Leopard до Mountain Lion и установил последнюю версию XCode (4.4 )

. Я скачалhttp://sourceforge.net/projects/mysql-python/

python setup.py build 

я получаю следующий вывод в терминале

оба следующих каталога существуют, я понятия не имею, как решить проблему с невозможностью выполнения clang...
