Last time I looked at Nix it had a problem with dealing with cross-compilation. The problem is mainly that many packages still use autotools which does not have a descriptive toolchain. Ultimately, it could provide a descriptive toolchain and then map that toolchain to the different build systems, which is similar to what cget does, but perhaps a separate tool to do this could be helpful so this could be shared among different package managers.
