A system has old versions of KDE and QT installed. Emerging KDE to upgrade to the new version with '-D' should also upgrade the QT dependency, so let's try... # emerge -Dp kdelibs These are the packages that would be merged, in order: Calculating dependencies ... done!

Have verified this to be the case in older 2.1.* versions of portage also.
Please post your "emerge --info".
Created attachment 184274 [details] emerge --info
[EDIT] In the original post, '# emerge kdepimlibs' should read '# emerge -Dp kdepimlibs' Thanks!
