This is just a rough and coarse outline, describing the basic working 
principle, it lacks many details and doesn't reflect the fact building 
the toolchains is a rolling and evolving process. I can't recommend 
anybody (esp. new-comers) following it.

That said, if not very being careful, it's pretty much guaranteed to 
kill an installation. It's one of the reasons why I am supplying binary 
packages and why OpenSource OS vendors are supplyling binary packages ;)
