[blocks B     ]  >x11-libs/qt-gui-4.4.2-r9999 (“>x11-libs/qt-gui-4.4.2-r9999″ is blocking x11-libs/qt-xmlpatterns-4.4.2, x11-libs/qt-script-4.4.2,
x11-libs/qt-dbus-4.4.2, x11-libs/qt-sql-4.4.2-r1, x11-libs/qt-qt3support-4.4.2, x11-libs/qt-svg-4.4.2, x11-libs/qt-test-4.4.2, x11-libs/qt-opengl-4.4.2,
x11-libs/qt-core-4.4.2-r2)

[blocks B     ]    <x11-libs/qt-gui-4.5.1 (“<x11-libs/qt-gui-4.5.1″ is blocking x11-libs/qt-opengl-4.5.1, x11-libs/qt-svg-4.5.1-r1, x11-libs/qt-script-4.5.1,
x11-libs/qt-dbus-4.5.1, x11-libs/qt-xmlpatterns-4.5.1, x11-libs/qt-test-4.5.1, x11-libs/qt-qt3support-4.5.1, x11-libs/qt-sql-4.5.1, x11-libs/qt-core-4.5.1)

this means that new Qt libraries are available and portage is trying to upgrade only *a part* of the ones you have installed.

this is bad because mixed versions of Qt packages (like qt-core-4.5.1 alongside qt-svg-4.4.2) can result in unexpected breakage.

unfortunately, at the moment this error is the only way we can prevent version mixing.

to get past the error, you can:

  • emerge -avDuN world
    • updating world tells portage to upgrade all Qt packages in one run
  • emerge -av1 `eix -I --only-names x11-libs/qt-`
    • if you don’t want to upgrade everything, you can use this command to upgrade all the installed Qt libraries

if you still have problems, don’t hesitate to comment and I’ll do my best to help :)
