Like it says, the files cannot be downloaded by portage. This is usually
because you have to accept some sort of licence agreement before
downloading. You need to download the file specified, probably from
https://developer.nvidia.com/cuDNN and place it in $DISTDIR
(/usr/portage/distfiles by default) then run the emerge command again.
