Hello people, i tried to install kde-meta-4.1.2 and i ran across a few
problems. The thing is that some packages are blocking packages required for
the installation

The following is output of portage when displaying the blocking packages

[uninstall    ] app-crypt/qca-1.0-r2  [?]
[blocks b     ] <app-crypt/qca-1.0-r3 ("<app-crypt/qca-1.0-r3" is blocking
app-crypt/qca-2.0.1-r1)
[blocks B     ] <=x11-libs/qt-4.4.0_alpha:4 ("<=x11-libs/qt-4.4.0_alpha:4"
is blocking x11-libs/qt-script-4.4.2, x11-libs/qt-dbus-4.4.2,
x11-libs/qt-qt3support-4.4.2, x11-libs/qt-sql-4.4.2, x11-libs/qt-gui-4.4.2,
x11-libs/qt-svg-4.4.2, x11-libs/qt-test-4.4.2, x11-libs/qt-core-4.4.2,
x11-libs/qt-webkit-4.4.2, x11-libs/qt-opengl-4.4.2)
[blocks B     ] <sys-fs/udev-114 ("<sys-fs/udev-114" is blocking
media-gfx/sane-backends-1.0.19-r2, media-libs/libgphoto2-2.4.2)

My usual solution for problems of this kind is to mercilessly unmerge any
packages that stand in my way, but, considering we are talking about
packages like qt and udev, i must admit i do not dare to follow my usual
strategy.

I guess the paths i can follow are masking some packages or unmerging some
packages, being confronted by such a decision and unsure of what i should
do, i decided to seek your advice.

Thanks very much in advance

Yours trully

Rafael
