Hi,everyone,I wanted to install KDE4 and meet a problem like this
:
 emerge kde

Linking CXX shared module ../../../../lib/kcm_kwinoptions.so
[ 45%] Built target kcm_kwinoptions
make: *** [all] Error 2
 *
 * ERROR: kde-base/kdebase-4.0.0 failed.

 *  The die message:

 *
 * If you need support, post the topmost build error, and the call stack if relevant.
 * A complete build log is located at '/var/tmp/portage/kde-base/kdebase-4.0.0/temp/build.log'.

and I searched for a while and try emerge -D kde,but when emerging kdenetwork:
