Использование MySQL с dev_appserver (Google App Engine) и службой Google SQL

Я использую Google App Engine и Google SQL Service и хотел бы использовать опцию

dev_appserver.py --mysql_user = имя пользователя myapp

чтобы использовать локальную базу данных MySQL для целей разработки и SQL Service в среде prod.

У меня установлен MySQLdb и работает:

/usr/bin>>python
Python 2.7.2 (v2.7.2:8527427914a2, Jun 11 2011, 15:22:34) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import MySQLdb
>>> 

Однако, когда я запускаю команду dev_appserver, я получаю следующую ошибку:

zipimporter('/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/MySQL_python-1.2.3-py2.7-macosx-10.6-intel.egg', 'MySQLdb/')
ERROR    2011-09-12 09:34:53,541 rdbms_mysqldb.py:90] The rdbms API is not available because the MySQLdb library could not be loaded.

Я проверил, что MySQL_python-1.2.3-py2.7-macosx-10.6-intel.egg находится в этом месте (/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site -пакеты/) и что он доступен.

Любая идея, что может вызвать эту ошибку?
