To follow up, after removing "qt" (by mistake), and all the qt-* packages I
could find, this is what I found when running "emerge -uDav world""

x11-libs/qt-gui:4

  ('ebuild', '/', 'x11-libs/qt-gui-4.5.3-r1', 'merge') conflicts with
    ~x11-libs/qt-gui-4.5.2[-debug] required by ('ebuild', '/',
'x11-libs/qt-webkit-4.5.2-r1', 'merge')

x11-libs/qt-sql:4

  ('ebuild', '/', 'x11-libs/qt-sql-4.5.3', 'merge') conflicts with
    >=x11-libs/qt-sql-4.5.0:4[mysql] required by ('installed', '/',
'app-office/akonadi-server-1.2.1', 'nomerge')

x11-libs/qt-core:4

  ('ebuild', '/', 'x11-libs/qt-core-4.5.3-r1', 'merge') conflicts with
    ~x11-libs/qt-core-4.5.2[qt3support,-debug] required by ('ebuild', '/',
'x11-libs/qt-sql-4.5.2', 'merge')

x11-libs/qt-dbus:4

  ('ebuild', '/', 'x11-libs/qt-dbus-4.5.3', 'merge') conflicts with
    ~x11-libs/qt-dbus-4.5.2[-debug] required by ('ebuild', '/',

media-libs/x264:0

  ('ebuild', '/', 'media-libs/x264-0.0.20090923', 'merge') conflicts with
    <media-libs/x264-0.0.20090908 required by ('installed', '/',
'media-video/avidemux-2.5.1-r2', 'nomerge')


!!! The following update(s) have been skipped due to unsatisfied
dependencies
!!! triggered by backtracking:

x11-libs/qt-assistant:4
x11-libs/qt-test:4
x11-libs/qt-svg:4
x11-libs/qt-script:4
x11-libs/qt-webkit:4
x11-libs/qt-opengl:4

Not sure where to go with this.

When I ran "emerge world" the re-installation of more than 250 packages was
begun.
