That is what I remember too and I think it was you explaining it but that was a while back. Here is the thing. After my last post, I stopped the emerge. I emerged one version of gcc and it emerged fine in the normal time of around 20 minutes. I then did a emerge -uvaDN world and it compiled the other version and the rest as it should. It seems when there is two versions of gcc to upgrade, something gets weird. When I do one at a time, it works fine. I'm just not sure why tho. Is it having two versions in world at the same time? Surely not. I been doing that for a long time and this double thing started a month or so ago. Thought it was a fluke at first. Weird huh? Dale :-) :-) -- I am only responsible for what I said ...
