Yes, you are right. The are actually a bunch of other library files

At the beginning, I used the .run installer, but thought to have cleaned
this up. Obviously, this was not the case. The are a few more files
installed on Sep 10 (mostly symbolic links). I've removed those and
reinstalled nvidia-smi. That fixed the problem.


Thanks a lot for the hint.
