uClinux build questions

To start off, I'm just new to build uClinux environment, so been learning curve but getting there. I followed instructions:

http://www.nioswiki.com/installnios2linux

but what I noticed when doing a make is that the userland programs aren't ready to compile. i.e. it is looking for build-busybox and the directory is really busybox, same for agetty and boa. Where do you tell it which userland programs you want to compile, and any idea why they don't 'just work' ?

We had this environment setup before on older code, and normally we would do a 'make romfs' after getting the toolchain setup, but that's where I get stuck.

Pointers?

Thanks!
