Installing Xcode 3 on Mountain Lion

Jeff Johnson:

You may find yourself needing to install Xcode 3 on Mountain Lion. I did. Perhaps you need the Mac OS X 10.6 SDK. Perhaps you need to build PowerPC code. Or perhaps you just hate the Xcode 4 GUI. In any case, the Xcode 3 installer won’t allow you to install on Mountain Lion, and even if you force it with the environment variable COMMAND_LINE_INSTALL, your Mac will kernel panic on the next boot, because Xcode 3 installs some kernel extensions that are not compatible with Mountain Lion.
