If you install Xcode 3 from the GUI on Lion, you'll end up with a bunch of random tools but not the actual Xcode Toolset. In that case, you can use the uninstall-dev-tools located in /Library/Developer/Shared (rather than /Developer/Library).
如果您从 Lion 上的 GUI 安装 Xcode 3，您最终会得到一堆随机工具，而不是实际的 Xcode 工具集。在这种情况下，您可以使用位于 /Library/Developer/Shared（而不是 /Developer/Library）中的卸载开发工具。

export COMMAND_LINE_INSTALL=1
open "/Volumes/Xcode and iOS SDK/Xcode and iOS SDK.mpkg"
