Well, this is basically what I had to do. I wouldn't call it a complete reinstall but it is pretty close. It's not like booting from a CD and starting from scratch. In the original thread, he got a lot of help and tried a lot of things including recompiling a lot of things from what I read. I mentioned this should be a last resort. This is time consuming to say it lightly. That said, it has worked well for me. Everything on my rig is working again. If he has to do this downgrade of gcc, then a emerge -e world and everything works again, I'm going to really wonder what the deal is with gcc. Just me running into problems is one thing but to have someone else have issues as well, that's makes me wonder. Is there something funny going on that only affects certain hardware or something like that? How would one test it to see what is wrong when it is only a couple or a few people? Dale :-) :-)
