It seems like it's backtracking, but in that case it's supposed to tell you about missed updates. You can use --backtrack=0 to disable backtracking: emerge -1u qt-sql --backtrack=0 Does that show the blockers?
*woha* This bug is quite hard to trigger. :-/ It definitively has something to do with the backtracking in combination with blockers. I've already upgraded the mentioned packages (and downgrading qt-*-packages is no option), so I tried to reproduce it by chrooting into my backup. :) (chroot) bluebird ~ # emerge -uDN @world [... snip ...] x11-libs/qt-sql fails due to PEBKAC (invalid symlinks in /usr/include). And now I am left with the following inconsistend state: (chroot) bluebird ~ # eix -I qt- -c [I] x11-libs/qt-core (4.7.1-r1(4)@13.02.2011): The Qt toolkit is a comprehensive C++ application development framework [U] x11-libs/qt-dbus (4.6.3(4)@12.12.2010 -> (~)4.7.1(4)): The DBus module for the Qt toolkit [U] x11-libs/qt-gui (4.6.3-r2(4)@12.12.2010 -> (~)4.7.1-r1(4)): The GUI module for the Qt toolkit [U] x11-libs/qt-multimedia (4.6.3(4)@31.01.2011 -> (~)4.7.1(4)): The Qt multimedia module [U] x11-libs/qt-opengl (4.6.3(4)@12.12.2010 -> (~)4.7.1(4)): The OpenGL module for the Qt toolkit [U] x11-libs/qt-qt3support (4.6.3(4)@12.12.2010 -> (~)4.7.1(4)): The Qt3 support module for the Qt toolkit [U] x11-libs/qt-script (4.6.3(4)@12.12.2010 -> (~)4.7.1-r1(4)): The ECMAScript module for the Qt toolkit [U] x11-libs/qt-sql (4.6.3-r2(4)@12.12.2010 -> (~)4.7.1-r1(4)): The SQL module for the Qt toolkit [U] x11-libs/qt-svg (4.6.3(4)@12.12.2010 -> (~)4.7.1-r1(4)): The SVG module for the Qt toolkit [U] x11-libs/qt-test (4.6.3(4)@12.12.2010 -> (~)4.7.1(4)): The testing framework module for the Qt toolkit [U] x11-libs/qt-webkit (4.6.3-r1(4)@12.12.2010 -> (~)4.7.1-r1(4)): The Webkit module for the Qt toolkit [U] x11-libs/qt-xmlpatterns (4.6.3(4)@12.12.2010 -> (~)4.7.1(4)): The patternist module for the Qt toolkit But this gives an error message: (chroot) bluebird ~ # emerge -1up qt-sql These are the packages that would be merged, in order: Calculating dependencies... done! !!!

Ok, closing as WORKSFORME until someone can reproduce it.
