Either **download from Cachix**:
```
nix-store -r /nix/store/kdd8wpy8nqwvbk88vfs3pvm8hay48pzg-libass-0.17.1 \
  --option binary-caches 'https://cache.nixos.org/ https://nix-community.cachix.org/' \
  --option trusted-public-keys '
  nix-community.cachix.org-1:mB9FSh9qf2dCimDSUo8Zy7bkq5CX+/rkCWyvRCYg3Fs=
  cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY=
  '
```
(The Cachix cache is only trusted for this store-path realization.)
For the Cachix download to work, your user must be in the `trusted-users` list or you can use `sudo` since root is effectively trusted.

Or, **build yourself**:
```
nix-build -A libass https://github.com/r-ryantm/nixpkgs/archive/5a11d74d175a7983137e912a3a4cfe0da4aa40d6.tar.gz
```

After you've downloaded or built it, look at the files and if there are any, run the binaries:
```
ls -la /nix/store/kdd8wpy8nqwvbk88vfs3pvm8hay48pzg-libass-0.17.1
ls -la /nix/store/kdd8wpy8nqwvbk88vfs3pvm8hay48pzg-libass-0.17.1/bin
```
