OK, I'll take care of the long version variant of the 
libnvidia-nvvm.so.#VERSION# symlink as well.

Once there is a new package version out, don't forget to remove these 
manually created links again (there is no guarantee that the package 
upgrade will "overwrite them"), otherwise you might run into problems 
later on ...

Did one of you try the 515 driver? I'd expect that the OpenCL problems 
started back then, at least there were some changes w.r.t. 
libnvidia-nvvm.so* ...

PS: since most libraries in the nvidia driver are not linked against all 
their dependencies but use dlopen for some optional libraries (that are 
only needed for certain operations), it's not trivial to get the 
dependencies in the Debian packages right ... especially if there are 
driver internal changes in the usage of these things ... or these libs 
are not used that often ...
