Thank you for your answer and sorry for the delay in replying to it. When I first read your comment, I wanted to write: "You've got it!" But now, when the issue is solved, I should acknowledge that the qtwebkit has not required -icu, it was just compiled with -icu by default and that created the blocker. > As far as I can tell from reading a couple bug reports, it looks like > you can rebuild qtwebkit with -gstreamer (since that's what causes > the !icu? blocker) and then you should be able to install chromium. > Apparently icu is pretty annoying. > > Alternatively, you could just uninstall qtwebkit if you're not using it > for anything. These your suggestions actually forced me to delay the answer, as I needed time to check which of my application packages depend on qtwebkit and if I really need gstreamer. Now, when the problem has been solved, it is not so important but nevertheless: 1. At least the app-text/goldendict, that I need very much, depends on qtwebkit. 2. I am not sure but my guess is that the gstreamer allows me to watch the video from youtube (partially), edX, cousera, etc. in a web-browser (I mainly use Firefox), as I never install any flash player to avoid too many "flashing" while browsing the Internet. (Would be interested to know if this my guess is correct.)
