I see the motivation now. Well, you can have a project-local nix file 
that imports its dependencies from the global expression - and you build 
it in the directory via "nix-build ./" (you probably don't want these 
things in your profile, maybe rather in a seprarate project-profile).

This way seems cleaner to me, because intuitively the project depends on 
nixpkgs, not the other way around. (You could also have e.g. a topgit 
branch for the project on top of nixpkgs, but it seems inferior to the 
solution above.)
