NetBSD needs a *very* minimal set of POSIX tools to build, e.g. you can get away with an sh(1) utility and a pretty basic make(1) tool. They have really done a magnificent job at constructing a build system that can bootstrap itself from a tiny set of build tools. FreeBSD also has _some_ of the necessary build glue to do similar sort of stuff, but AFAIK we only support cross-building from one FreeBSD architecture to another FreeBSD architecture. So you need to have at least *some* version of FreeBSD to build another.
