Quanta inherits the kde.eclass and the kde.eclass depends on ~kde-base/kde-env-3; however, you can install kde-env without the rest of qt/kde. Therefore, emerge will attempt to compile quanta, and fail, if qt is not installed. Reproducible: Always Steps to Reproduce: 1. On a system without qt or kde, emerge kde-env 2. emerge quanta 3. Actual Results: ./configure fails with: checking for Qt... configure: error: Qt (>= Qt 3.1 (20021021)) (headers and libraries) not found. Please check your installation! Expected Results: Emerge should install qt and other packages quanta requires.
should be fixed now
