Unreal 4.11 Source custom build fails to launch on mac

The latest 4.11 preview builds successfully, but fails to launch correctly.

2016.01.22-01.33.16:650][ 0]LogDerivedDataCache: Unable to find inner node Shared for hierarchical cache Hierarchy.
Fatal error: [File:/Users/xxx/Github/UnrealEngine/Engine/Source/Runtime/Engine/Private/ShaderCompiler/ShaderCompiler.cpp] [Line: 1302]
Couldn’t launch /Users/xxxx/Github/UnrealEngine/Engine/Binaries/Mac/ShaderCompileWorker! Make sure the file is in your binaries folder.

Looks like ShaderCompileWorker is not built on mac source build?

Thanks for any help

I met same error.
here is my solution:
open terminal,
change dir to UnrealEngine
then enter these command below:

./Engine/Build/BatchFiles/Mac/Build.sh ShaderCompileWorker Mac Development -verbose

Thank you Captains 510!!! Worked

You can also build it from XCode, as I just found out.
