The trick is to do the ABSOLUTE MINIMUM each step.
Can you "emerge portage"? Given the elephant in the room that is all the python changes, if that works you're probably 90% of the way there. Do you need to update the system profile? Update it to a very basic profile and "emerge @system". NO --deep, NO --new-use, nothing like that. If portage says it can update some things but not others, then tell it to update what it can. Normally I'd "emerge -C" any blockers, but with a minimal system that's probably not wise. Once that's done, select your real profile that you want, and again do a basic "emerge @system". Followed by "emerge @world". Now do your full-blown "emerge --deep --new-use", depclean, new kernel, all that sort of stuff. Cheers, Wol
