I’m not seeing an error? There’s just no updates, you are at the latest versions of everything.

sorry this is the error when I am building blender:

CMake Error at CMakeLists.txt:964 (message):
Cycles OSL requires WITH_LLVM, the library may not have been found.
Configure LLVM or disable WITH_CYCLES_OSL

– Configuring incomplete, errors occurred!

looks like it may have had some issues getting the required libraries, try the manual instructions to get them from our wiki over here.
