Ok, as I said earlier I’m currently reinstalling my system from scratch (to finally and completly get rid of stupid eselect-compiler).
The first attempt was a bit, ehrm, error-prone (as in unpacking stage3-i686-2006.0.tar.bz2, chrooting to that and running emerge -ek system). Result was a b0rked chroot after the first two packages (heh, it was pulling in =sys-libs/glibc-2.4-r3 as the second package, thus everything that hasn’t been merged from my binpkg-repo and still originating from the snapshot being broken).
After removing the whole stuff again, again unpacking the stage3 tarball I simply untar’ed all system related (or those that I thought were vital) tarballs into the /mnt/gentoo directory.
*arg* after I finished writing those lines, I tried sudo gcc-config 6 to see if that would work. And what happens ?
Same old, same old …
* Switching cross-compiler to i686-linux-gnu-4.1.1 [ ok ]
