Installation of a package returns Undefined Variable Error

Help

I have tried to install the ollama package from the nix repository. For some odd reason the installation fails. The build is successful when I comment that line out.

output of nix-shell -p nix-info --run "nix-info -m"

Looks like you have not updated in the last 6 months… Perhaps that is the reason.
