This page shows you another way to get the latest Portage tree from within your install chroot.
To use this method, you download a snapshot snapshots from inside the chroot, extract it to the /usr directory, use git to activate the funtoo.org branch, and then run emerge --sync to quickly download the very latest updates to the tree:
# cd /usr
# wget http://ftp.osuosl.org/pub/funtoo/funtoo-current/snapshots/portage-latest.tar.xz
# tar xf portage-latest.tar.xz
# rm portage-latest.tar.xz
# cd /usr/portage
# git checkout funtoo.org
# emerge --sync
This method uses wget (HTTP) to grab the vast majority of data and could be faster
or more reliable for some users.
