A couple of minor points I noticed:
You'll also want to edit /Developer/Library/Xcode/Plug-ins/llvm-gcc  
4.2.xcplugin/Contents/Resources/llvmgcc42.xcspec and comment out the

     OptionsForSDKPackages = {
         sdk_package_flags = "-isysroot $(SDKROOT)";
     };

because if you have llvm-gcc selected as a compiler in Xcode and you  
do scan-build for your project clang won't accept more than one - 
isysroot option and will fail the scan-build.

Naturally you'll also want to add /Developer/usr/bin and /Developer/ 
usr/local/bin to your path :)
