You need to log into the developer.apple.com to download the "Command line tools" for Lion or Mtn Lion. Note that the OS X SDKs do NOT come with these tools. Just the compiler and associate tools. So if you are building anything that needs to link against the OS X SDKS (like Qt..) you still need to install Xcode.

 Note that you can build the Latest Clang yourself. I *think* you need OS X 10.7 to do this though. Not sure on that last one. But again, unless you are building something basically trivial that does NOT rely on the OS X SDK's then you still need to install Xcode.

Just some stuff that I have found out in the last few months.
