emerge kde 3.5 splitted ebuilds

Kde 3.5 is masked as ~x86 in current portage. If you dislike to update your whole system to unstable ~x86, you can add the kde packages to `/etc/portage/package.keywords, just like this:

 for x in `ls -l /usr/portage/kde-base/ | grep ^d | cut -c 52-` ; do echo kde-base/$x ~x86 >> /etc/portage/package.keywords ; done

And you might need to add some other packages to /etc/portage/package.keywords manually:

echo "sys-apps/pmount ~x86
sys-apps/dbus ~x86
sys-apps/hal ~x86
sys-fs/udev ~x86
app-text/poppler ~x86" >> /etc/portage/package.keywords

Update the world

emerge -u world

Remove the obsolete kde package to save the disk space:

emerge -P `cat /var/lib/portage/world | grep ^kde`
