You must have done something more than just emerge --sync followed by emerge -uDU @world. OR you must have had old package.use entries setting duplicate USE flags already. > I missed out the stuff at the start of the news item, sorry, but see > below ... > > Giveb that I don't "do" Python, I've got nothing in make.conf that > mentions python.

I'm confused and baffled that, when a news item describes some blocks of code as "the package.use samples provided below", you are totally lost and declare that you don't "do" python as it's double dutch to you. And why on earth would you assume they are comments? You don't need to know python and aren't expected to either. The news item describes the fact that: - a group of packages using the python programming language, are switching their versioned USE flags, here's the correct way to migrate the USE - it involves building many packages for the changed USE. Rebuilding many packages at the same time can sometimes result in complex issues, these are a USE_EXPAND and can be migrated in stages, which is safer. -- Eli Schwartz
