Build failure: `mac-app-util` -> `sbcl-2.6.0` -> `system-cl-interpol`

[sheeeng]

Cross-post NixOS/nixpkgs#483454 issue here as it is a dependency of mac-app-util. I'm not sure how to troubleshoot this issue.

@sheeeng I have the same issue and was able to temporarily work around it by removing the pin here.

[hraban]

thansk for the bug report. In general overriding the nixpkgs pin for mac-app-utils (and other flakes) is a "buyer beware" mode of use. I only test with the nixpkgs pinned in the flake.lock for mac-app-utils.

That being said it'd be good for this to work on latest nixpkgs-unstable and stable, so I'll have a look to see how to fix it. In the mean time though, just using the pinned nixpkgs from mac-app-utils is definitely the recommended way to use this.
