我刚刚在64位的Snow Leopard上编译了Qt4.6的最新预览，没有任何重大问题。

现在，我正在尝试使用River Bank网站上的最新快照为PyQt4.6做同样的事情。但是，编译器退出时出现以下问题：

这是PyQt4尝试访问Qt4类的私有成员时出错吗？有没有人成功在Snow Leopard上编译PyQt4？

在更改日志中，昨天我在专门针对Snow Leopard的开发快照中看到了Phil（PyQt的维护者）has issued fixes：
2009/09/14 12:12:49 phil 修复了64位的Snow Leopard 系统。添加 QObject.pyqtConfigure（）。
您使用昨天构建的PyQt吗？
This thread on the mailinglist也非常有趣。
PyQt编译问题似乎是由Snow Leopards默认的64位编译和它随附的64/32位混合版Python引起的。
如果事情继续出错，我会将你的问题提交到这个邮件列表（这样他们就可以得到修复 - 希望如此）并尝试（暂时）以32位的方式重建Qt和PyQt（可能还有python）（ -m32编译器标志）如果你现在需要它。

我让PyQt 4.6.2使用64位Python 2.6.1。我在这里发布了说明：http://mpastell.com/2009/11/24/pyqt-4-6-2-with-snow-leopard/

您可能希望使用自制项目中的PyQt：直接构建，托管依赖项。
在我的MBP Unibody上运行正常，全部是64位。
