[Nix-dev] ./configure && make && make install

[Sergey Mironov]

Let me reformulate my question: Let's say nixpkgs contains two packages,
package A depends on B (B may be some library). If I write

environment.systemPackages = [A];

what will nixos do for package B? Have I got a tool which will tell me that
B is installed but not exposed (linked to profile) or something like that?
Looks like nix-env knows nothing about system packages and the only way I
know so far to see B's presence is to type 'ldd A'.
