The 169.09 ebuild recently added to portage is just a version bump. It ignores new features present in the driver for CUDA applications. Bug #199671 has a few comments to this effect, in particular http://bugs.gentoo.org/show_bug.cgi?id=199671#c4 Namely, libcuda.so must be installed as well as a couple header files. Reproducible: Always Steps to Reproduce: 1. emerge nvidia-drivers 2. ls /usr/lib/libcuda.so 3. ls /usr/include/*cuda* Actual Results: No such file or directory Expected Results: /usr/lib/libcuda.so cuda.h cudaGL.h
fixed in 169.09-r1
