build.log

After upgrading app-misc/ddcutil-0.9.9, portage warned me about the preserved libs /usr/lib64/libddcutil.so.0 and /usr/lib64/libddcutil.so.0.0.0. I run emerge @preserved-rebuild which caused a rebuild of kde-plasma/powerdevil. However, this failed with the attached build log. This is the error message:
