It says it's going to downgrade nvidia-cuda-sdk,but it doesn't say why.
For that:

$ eix dev-util/nvidia-cuda-sdk
* dev-util/nvidia-cuda-sdk
     Available versions:  2.02.0807.1535^b (~)4.2.9-r2 (~)5.0.35-r1
{+cuda debug +doc emulation +examples opencl}
     Homepage:            http://developer.nvidia.com/cuda
     Description:         NVIDIA CUDA Software Development Kit



What's in your ACCEPT_KEYWORDS?
My guess is you have a stable system and cuda is not unmasked
