I'm having trouble getting an app to run on x86_64-darwin derivation here: https://github.com/gigamonster256/opencode/blob/48050d51580cc332979c589e2ed260984f240cd6/nix/opencode.nix

opencode> 34 | export function systemArchitectureSync() {
opencode> 35 |  const {arch, platform, env} = process;
opencode> 36 |

any advice for making sure the sysctl command is found? some sort of wrapProgram? adding sysctl to buildInputs didnt seem to make a difference

Randy I had a look at your WIP progress swift build mk2 branch and had a bit of skim over, It's looking good.

However I am still not too sure if the by-name thing follows RFC 140 after reading your code by-name/sw/swift/by-name/sw/<package> and the rfc.
