Error (Failed to compile default material) during run of 4.11 on MacOSX

in 4.11 on OS X, clean git status (no local changes), no issues building.

running always stumbles on the following:

[2015.12.17-00.45.39:840] 0]LogShaderCompilers:Warning: InstancedStereo.usf(100): error: static variables must be declared const
[2015.12.17-00.45.39:840] 0]LogShaderCompilers:Warning: Common.usf(894): warning: implicit truncation from ‘vec3’ to ‘vec2’
Fatal error: [File:/Users/sshinderman/dev/UnrealEngine/Engine/Source/Runtime/Engine/Private/ShaderCompiler/ShaderCompiler.cpp] [Line: 1539]
Failed to compile default material /Engine/EngineMaterials/WorldGridMaterial.WorldGridMaterial!

since this is a default shader guessing it’s not a cache or previous build issue.
any one see something similar or know a workaround?

-thanks!

I meet the exactly same issue when packaging the unreal sample by using OpenGL. It seems that the opengl doesn’t support that kind of ‘static’ declaration. I haven’t found any easy fix yet.
