My problem is the same as bug#206787 (marked as dup of this bug)
 * 
 * ERROR: app-misc/strigi-0.5.7 failed.
 * Call stack:

 *  The die message:

 except the package complaining is app-misc/strigi-0.5.7 instead of soprano
when trying to emerge kde-4.

If further info needed let me know  :-0

I had the same problem here and found a dirty hack to get around. IMHO the
trouble seems to come from the "split ebuilds" of qt-4. I did the following
steps:

1. faked the provided USE flags of the qt-4 package:

mkdir -p /usr/local/portage/x11-libs
cd /usr/local/portage/x11-libs
cp -a /usr/portage/x11-libs/qt .
cd qt
nano -w qt-4.4.0_rc1.ebuild

changed -> IUSE="opengl qt3support"
into -> IUSE="opengl qt3support accessibility dbus debug gif jpeg png ssl zlib"

2. now I autounmask'ed and tried to build kdelibs like before, including all
dependencies, especially the various qt-xyz packages. The build failed,
probably due to the lack of features in the generated qt install, but portage
now thinks that the qt dependencies are successfully installed.

3. trown away the broken qt stuff:

cd /usr/lib
mv qt4 qt4-broken

4. then I built qt4 on my own, using the configure options that I copied from
"emerge qt-core", but with less "-noxxx" options:

cd /var/tmp
tar -xvzf /usr/portage/distfiles/qt-x11-preview-opensource-src-4.4.0-tp1.tar.gz
cd qt-x11-preview-opensource-src-4.4.0-tp1
./configure -debug -stl -verbose -largefile \
        -confirm-license -no-rpath \
        -prefix /usr \
        -bindir /usr/bin  \
        -libdir /usr/lib/qt4 \
        -datadir /usr/share/qt4 \
        -docdir /usr/share/doc/qt-4.4.0_rc1 \
        -headerdir /usr/include/qt4 \
        -plugindir /usr/lib/qt4/plugins \
        -sysconfdir /etc/qt4 \
        -translationdir /usr/share/qt4/translations \
        -examplesdir /usr/share/qt4/examples \
        -demosdir /usr/share/qt4/demos \
        -fast -reduce-relocations \
        -nomake examples -nomake demos \
        -openssl -glib -qt3support
make
make install

5. after that I was able to successfully emerge kdelibs and so on, the whole
"kde-meta" emerged fine.

confirming bug

CCing qt aswell as since this is partly a problem with x11-libs/qt-* features
being overridden by x11-libs/qt-core.
Ex: x11-libs/qt-gui with USE accessibility emerges fine but x11-libs/qt-core
has #define QT_NO_ACCESSIBILITY in /usr/include/qt4/Qt/qfeatures.h hence KDE
fails.

It's not only the accessibility. You also get trouble when qt-core is not built
with X Session Management (-no-sm). I propose to put a USE-Flag "X" (probably
also one for "accessibility") to qt-core, to enable the neccessary
configuration for building kde4 correctly. If you want to keep qt-core clean
from X-deps (server-usage) this must (in my eyes) be done optional - with
USE-Flags.

As the way to finish building qt is quite long it would be great when at least
qt-core tells the user in a nice Warning, that he MUST build qt-core with these
USE-Flags, when he/she wants to build kde4. Or is it possible yet to cancel a
"emerge kde4" when qt-core does not have these neccessary flags enabled?

KDE 4.0.2 now compiles fine with Qt 4.4, marking as FIXED.
