The solution is a little more complex than in Michael's reply and this may take a while :-) . Normally with blockers one looks in the ebuild to see what you may and may not do, this is often enough info. The contents of /etc/portage/* is seldom useful here as blockers almost always mean you have specified two things that cannot co-exist. In your case, you have run into monolithic and -meta kde ebuilds. Guess what - you already have the kompare binaries, despite the fact that kde-base/kompare is not installed. That's because they are actually part of kdesdk. There are two ways I would have gone about finding this out: a. 'equery depends kompare' would have said that kdesdk-meta depends on it, if it were installed (which it isn't on your machine). b. Looking into the ebuild for kdesdk-meta shows: RDEPEND=" ... $(deprange $PV $MAXKDEVER kde-base/kompare) ... " So the -meta package installs kompare, therefore the monolithic package will too. Essentially you are trying to install one of the individual packages from a -meta package at the same time as a corresponding monolithic package,and portage is correctly refusing to let you do this. How did I immediately know that this is the cause? School of hard knocks :-) From experience I have a good idea of the name of the 15 or so KDE monolithic packages, and the general rule I follow is that blockers related to kde are usually conflicts between -meta and monolithic ebuilds. Roll on KDE4 when this monolithic nonsense will go away and there will only be -meta ebuilds. alan > > # emerge --search kompare > Searching... > [ Results for search key : kompare ] > [ Applications found : 1 ] > > * kde-base/kompare > Latest version available: 3.5.7 > Latest version installed: [ Not Installed ] > Size of files: 5,078 kB > Homepage: http://www.kde.org/ > Description: KDE: A program to view the differences > between files and optionally generate a diff License: GPL-2 > > # emerge --search '%^kdesdk$' > Searching... > [ Results for search key : ^kdesdk$ ] > [ Applications found : 1 ] > > * kde-base/kdesdk > Latest version available: 3.5.7 > Latest version installed: 3.5.7 > Size of files: 5,088 kB > Homepage: http://www.kde.org/ > Description: KDE SDK: Cervisia, KBabel, KCachegrind, > Kompare, Umbrello,...
