There is probably no problem with your Gentoo Prefix installation. It
looks like you are trying to install some packages that have never
been tested and/or ported to to x64-macos architecture. You will have
various levels of success here, ranging from easy (just add the
keyword and it will work) to very difficult (rewrite the poorly
written scientific package build system to support an offset). At
least, if the package exists in Macports, it has some chance of
success in Gentoo Prefix :)

Actually, there is no 'stable' concept in Gentoo Prefix. You are
always using latest version of packages. The Gentoo Prefix team simply
does not have the staff to maintain different stable/unstable trees.
It normally works out pretty well by leveraging some of the work of
Gentoo Linux developers and rely on the fact that massively broken
packages do not appear in ~arch on a often.

Hard to say the problem with the latest version. Did you look at the
bug tracker or file an issue?

If you have successfully bootstrapped, you actually have several
packages installed :)

Hope that helps a little bit,
