The make-native is required on Fedora14. So you don't need that step and
Instead you could directly:
	Bitbake poky-image-sato

Btw, could you post your errors?

For native packages, yes the host compiler from your distribution is expected btw.

This makes me a bit confused what you're tempting to do. Did you try to build
a complete sato image, or want to use pre-built image and downloard toolchain
to develop application? For the former you don't need the later /opt/poky
stuff. For the latter you don't need build any native packages since all the toolchains
are already there.
