OpenFang v0.6.0 cannot be built using the official Nix flake.nix

[FrantaNautilus]

Description

OpenFang build using flake.nix fails due to missing dependencies. This causes the OpenFang to be unavailable for NixOS users and users of Nix package manager.

Fix for this bug is in PR #1086

Expected Behavior

The official flake.nix is expected to provide functional build instructions.

Steps to Reproduce

1. clone OpenFang repository
2. run nix build .#openfang-cli
3. build fails due to missing dependency

OpenFang Version

0.6.0

Operating System

Linux (x86_64)
