I don't follow. 2.31 > 2.13, no?

ls is not the best tool to analyze runtime dependencies with Nix.

$ nix-store -q --references 
/nix/store/m1krjlz0bhps862qp6cjflhlw4fkhsyr-freerouter-native-22.7.16 | grep 
glibc
/nix/store/33idnvrkvfgd5lsx2pwgwwi955adl6sk-glibc-2.31

It depends which compiler is used to build the package.
