Note that there may be a bug in Xcode 4.4's handling of installing the command-line tools -- at least under OS X Lion (10.7.4): I did use the Xcode Preferences to install the command-line tools, but still in a Terminal session clang showed as the old version; and when I reopened Xcode and its Preferences, it did not indicate the command-line tools as installed. So instead I went to https://developer.apple.com/downloads/index.action, selected "Command Line Tools (OS X Lion) for Xcode - July 2012", downloaded it, and installed it from the downloaded .dmg. Now I do have the current version of the command-line tools installed (e.g., clang is version 4.0), and the Xcode app Preferences does show the tools as installed.
