Interesting, I’ll try to repro! For clarity, each “derivation” (lets say package) builds in its own hermetically sealed filesystem with its own dependencies. So conflicts in build system configuration shouldn’t be possible unless those packages are doing something impure (unlikely since the Nixpkgs CI tests for it) or the end user is doing something impure (still really hard to do).

on github this was my config: https://github.com/dankobg/nixos-conf. I had that in home.nix. They both couldn't be listed in that apps array at same time, gearlever specifed and smile commented works and vice versa. But doing nix shell -p with both worked together. I didn't have patience to check what was the problem since maybe it's some of the other apps as well.

I see the conflict warning you're referring to, but I can confirm that in my bare minimum repro, those packages can be installed in a system alongside each other, and the warning stays just a warning. I think both packages can be improved by filtering the meson.build file out of the stuff that is exported from each package into the environment. I'll need to investigate that more.

As far as your overall problem goes however, there's likely something else at play. You've nerd sniped me now, so I'll spend some time when I have some next to try to build a test harness for your exact config.
