This is no Gentoo for Zaurus install, it is a embedded uclibc stage1 that compiled the necessary software.
This is more a experiment and far from working. I wrote a howto, until now it leads until emerge system.
The devs say, that they want to review it and it might become a guide of how to bring gentoo on the zaurus.
But as I said, the X-Server is not working and I don't know how to bring gentoo on the zaurus that it is bootable.
Mostly portage is working as on the x86, it produces arm code optimised for xscale.
There are a few flaws, but most of the packages work.
