How to get a different version of a library with Nixpacks?

Hey! I'm trying to deploy a Django webapp that converts an Excel file to LaTeX code. The conversion works fine locally, but I get the following error when trying to convert during deployment: I think that I need to specify my version of zlib to 1.2.11 to match the Lua package that is installed, but I am unsure of how to do so. I've included my railway.json file for reference. { "$schema": "https://schema.up.railway.app/railway.schema.json", "build": { "builder": "NIXPACKS", "nixpacksPlan": { "phases": { "setup": { "aptPkgs": ["...", "texlive-full", "wget"], "cmds": [ "wget https://zlib.net/fossils/zlib-1.2.11.tar.gz && tar -xzf zlib-1.2.11.tar.gz && cd zlib-1.2.11 && ./configure && make && sudo make install" ] } } } }, "deploy": { "startCommand": "python manage.py migrate && python manage.py collectstatic --noinput && gunicorn layoutGenerator.wsgi", "restartPolicyType": "ON_FAILURE", "restartPolicyMaxRetries": 10 } } Service ID: bc0601b0-5427-4902-accd-52ebac13d6f2

Sorry, to specify the error is at the bottom of the attached Deployment Log.
