You're not supposed to run "depmod" outside of the builder of 
kernel-modules because it's impure (it ends up overwriting the depmod 
files generated by the builder).

Note that kernel-modules' builder does put a / at the end of $MODULE_DIR:

 
https://svn.nixos.org/repos/nix/nixpkgs/trunk/pkgs/os-specific/linux/module-init-tools/aggregator.nix

If you want to add additional modules to the kernel configuration, you 
should add them to the boot.extraModulePackages option and run 
"nixos-rebuild switch".
