Ruby 如何将mysql数据库上传到phpfog？

我已经创建了一个，我想上传到phpfog上，但是在第一步上传我的数据库时遇到了麻烦，我赢得了7 x64，我用ruby下载并安装了命令提示符，同时创建了一个隧道：

`C:\wamp\www\myapp>af tunnel
[WARNING] DL is deprecated, please use Fiddle
To use `af tunnel', you must first install Caldecott:

        gem install caldecott

Note that you'll need a C compiler. If you're on OS X, Xcode
will provide one. If you're on Windows, try DevKit.

This manual step will be removed in the future.

Error: Caldecott is not installed.`

但在安装caldecott时-

`C:\wamp\www\myapp>gem install caldecott
Fetching: eventmachine-1.0.3.gem (100%)
ERROR:  Error installing caldecott:
        The 'eventmachine' native gem requires installed build tools.

Please update your PATH to include build tools or download the DevKit
from 'http://rubyinstaller.org/downloads' and follow the instructions
at 'http://github.com/oneclick/rubyinstaller/wiki/Development-Kit'`

有人能帮我完成吗？
