Either download from Cachix:

nix-store -r /nix/store/d4w0psnijfsmghnay7qsg5b5nppj45p3-libyaml-0.2.3 \
  --option binary-caches 'https://cache.nixos.org/ https://r-ryantm.cachix.org/' \

(r-ryantm's 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 libyaml https://github.com/r-ryantm/nixpkgs/archive/3e2f26f6158640a1577dab5c72816b15ac0a8cf7.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/d4w0psnijfsmghnay7qsg5b5nppj45p3-libyaml-0.2.3
ls -la /nix/store/d4w0psnijfsmghnay7qsg5b5nppj45p3-libyaml-0.2.3/bin
