Yes. I also think the wiki is a bit confusing here. We should really try to enforce new people using the .bat first (it's way easier to use). > > ----emerge qt---- > 1.

New base path is "http://dev.mysql.com/get/Downloads/";, right? NFM, can't comment on the rest. But please continue reporting bugs and or providing patches, highly appreciated!
