I bootstrapped on Fedora 14 last week by skipping all
./bootstrap-prefix.sh commands apart from tree and portage, and that
worked fine.

Skipping the emerge of compiler and linker is really going to cause
trouble, since Gentoo Prefix uses modified versions that make sure all
the tools from the Prefix are found.  This is an essential bit of Gentoo
Prefix, that distinguishes it from all other solutions that are around,
because it means you don't have to do anything special to make your
libraries and tools being found, once you're in the Prefix environment.
