Currently emerge allows to clean the build folder and its temporary files. I might be useful to have an option to clean all installed files, so that to be able to launch another compilation, e.g. from Debug, to compile Release packages. Reproducible: Always Steps to Reproduce: 1.emerge --buildtype=Debug okular 2.emerge --offline --buildtype=Release Actual Results: Step 2 fails. Expected Results: Between step 1 and 2 an emerge --cleaninstalled is needed to delete installed files
Hm, this won't make to much sense since for switching between Debug and Release/RelWithDebInfo you need to delete everything anyway (you only can keep source/download dirs, the emerge dir and of course etc\kdesettings.bat).
