Per the ebuild commit message: "Upstream only supports CUDA 8 with this release" However, anything older than CUDA 9 does not support gcc > 5 and fails with the following error: #error -- unsupported GNU version! gcc versions later than 5 are not supported! Since gcc 6.4.0 is now the default in Gentoo, it is no longer possible to build with USE=cuda. Reproducible: Always
I am not sure, if this is finally a duplicate of #639384, or should be taken as new ticket.

Would you be able to edit the ebuild to remove the hard depend on CUDA 8 to try CUDA 9? If this works, then I can change the ebuild. I think Blender 2.79 fixes this issue. BTW, this is one reason I really don't like CUDA.
