Hi there,
i try to install steam using nixos. I am running the unstable nixos channel. My smallest reproducer is at the moment to install it in nix-shell. I get the same errors by enabling the steam program section.
exammple:
NIXPKGS_ALLOW_UNFREE=1 nix-shell -p steamcmd
these 7 derivations will be built:

I am totally out of clue how to debug there anything. When i try to install libidn2 independently, everything works fine. I just discover, that this uses another nix-store hash, than the one, thas is requested during the steam build. So i not really know how to specifically rebuild the problem with more debug info.
nix-build '<nixpkgs>' -A libidn2

Which further information can i provide here, for necessary insights?
