app engine helper for django

[SuperFC]

将下载好的helper模块解压，并且安装了Pythong for Windows扩展。为了确认环境设置正确，于是开启服务做测试，结果出现意外了。输入python manage.py runserver之后出错，错误如下：

WARNING:root:No ssl package found. urlfetch will not be able to validate SSL certificates.
WARNING:root:The rdbms API is not available because the MySQLdb library could not be loaded.
Traceback (most recent call last):
File "manage.py", line 18, in <module>

appconfig, unused_matcher = dev_appserver.LoadAppConfig(PARENT_DIR, {})

各位看看如何解决？
