>Description:
lutok fails to compile because it seems like it's accessing headers it's not supposed to (private ones):

cc1plus: all warnings being treated as errors^M

I will file an upstream bug (if one doesn't already exist), as this will likely hit us on FreeBSD if someone tries compiling the lutok port with a newer copy of g++ (which we do for arm64, powerpc*, etc as they still don't work with clang).
>How-To-Repeat:
Run the following commands as root:

echo MKKYUA=yes >> /etc/mk.conf
cd /path/to/src
./build.sh tools
./build.sh build
>Fix:
Either disable warnings, or fix the offending code to not use private C++ interfaces.
