Here's excellent advice: Do not install KDE-4.5 yet wait for 4.5.1 First, it's in an overlay, so when 4.5 hits the tree you will unmerge the whole lot again and redo it. How many spare cycles you got? If you have 4.4.5 installed from portage you will likely hit clashes with the overlay. There's were never pleasant in the 4.[23] era, I don't see that changing. 4.5.0 has some pretty severe regressions, bad enough for QA to not put it in the tree 4.5.0 does not have the kdepim suite - this might not apply to you. I can just imagine the akonadi updates when 4.5.1 hits the tree.... You gotta ask yourself "Is there a COMPELLING need for 4.5.0 other than it's brand new and shiny?" -- alan dot mckinnon at gmail dot com
