Now I've changed that to the same locale en_US.iso88591 that is used in non-root accounts on my machine. With that I rebuild Python3.1. And now, the error is gone. A bit strange. I came along this problem when I tried to emerge the new package app-portage/smart-live-rebuild This fails because the author's name contain non-ascii (even non latin1) characters. The author (Michał Górny) sent me a patch to distutils.eclass and after generating an utf-8 locale LANG=en_US.utf-8 emerge -v app-portage/smart-live-rebuild finally succeeded. He says, it's a Python problem. Have a nice weekend, Helmut.

(DON'T DISABLE THIS UNLESS YOU KNOW WHAT YOU'RE DOING) So, I have U- but I+ on wide-unicode What does that mean? I just re-emerged python:3.1 as a test, and I see exactly the same but I don't get that error. For some reason site.py certainly thinks your python3 is built without wide-unicode. Have you tried re-installing python3 just for fun? You could try deleting site.pyc and site.pyo as an easy test.

Thanks, unfortunately I don't understand the output I've got [ Legend : U - final flag setting for installation] [: I - package is installed with flag ] [ Colors : set, unset ] * Found these USE flags for dev-lang/python-3.1.3: . - + wide-unicode : Enable wide Unicode implementation which uses 4- byte Unicode characters. Switching of this USE flag changes ABI of Python and requires reinstallation of many Python modules.
