A little help building cuprate

Hey guys, i could use some help. I am trying to build cuprate: https://github.com/Cuprate/cuprate/ [https://github.com/Cuprate/cuprate/] with the instructions found in https://github.com/Cuprate/cuprate/pull/728/changes/48ee1bb9ed2dc3a0d7b53f66bb48f6273c964a26 [https://github.com/Cuprate/cuprate/pull/728/changes/48ee1bb9ed2dc3a0d7b53f66bb48f6273c964a26] It builds fine, but when attempting to run it i get [nix-shell:~/build/cuprate/cuprate/target/release]$ ./cuprated -h ./cuprated: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory [nix-shell:~/build/cuprate/cuprate/target/release]$
