Maaaaaaan, use search next time, Qt5 is not released yet (http://qt-project.org/wiki/Qt_5.0): Alpha released on April 3, 2012. Beta release expected by April – May. Final release expected by the end of June. And there are few threads that mentioned Qt5 here. But if you still want Qt5 components - free to add repo: http://qtlabs.org.br/~lmoura/qt5/conf/ And please, please, please next time use google and search on the forum before asking, on those kinda questions you can find answer in 5 minutes of search, instead of just making new threads, polluting forum and waiting till someone would do instead of you(yes it would take more time to write post and wait)
