The preflink guide recommends installing versions of xfree. Reproducible: Always Steps to Reproduce: 1. 2. 3. Actual Results: "If you are having trouble with prelinking QT/KDE, then first try upgrading to >=x11-base/xfree-4.2.1-r2 and >=x11-libs/qt-3.1.0-r1. If QT still fails then try compiling QT without xinerama support by adding myconf="-no-xinerama ${myconf}" in the qt ebuild." Expected Results: Should be changed to "...try updating to the latest version of xorg-x11..."
Removed all obsoleted xfree/qt/glibc thingies. They all seem to be resolved in subsequent versions.
