torch-bin failing with:

auto-patchelf: 1 dependencies could not be satisfied
error: auto-patchelf could not satisfy dependency libcusparseLt.so.0 wanted by /nix/store/1lr2jw9kl3p1kkjshz7ihs8mwgvw556i-python3.12-torch-2.6.0/lib/python3.12/site-packages/torch/lib/libtorch_cuda.so
auto-patchelf failed to find all the required dependencies.

cc @SomeoneSerge @ConnorBaker do you know which library needs to be added ?

@zeuner I'm having some issues with the process you have introduced in #277789.

I think it will work using the latest git-unroll, updated in #377956

GCC 14 ?

It looks like libcusparseLt.so is now a hard dependency:

error: auto-patchelf could not satisfy dependency libcusparseLt.so.0 wanted by /nix/store/1lr2jw9kl3p1kkjshz7ihs8mwgvw556i-python3.12-torch-2.6.0/lib/python3.12/site-packages/torch/lib/libtorch_cuda.so

If I understand correctly, we need to wait for #306172.
See #270446.
