According to configure, app-cdr/k3b-1.0_pre1 seems to depend on libdvdread: ... checking whether lrint is declared... no checking whether lrintf is declared... no checking dvdread/dvd_reader.h usability... no checking dvdread/dvd_reader.h presence... no checking for dvdread/dvd_reader.h... no configure: error: Could not find libdvdread. Please install. !!! Please attach the following file when filing a report to bugs.gentoo.org: !!! /var/tmp/portage/k3b-1.0_pre1/work/k3b-1.0pre1/config.log !!! ERROR: app-cdr/k3b-1.0_pre1 failed. Therefore, a dependency should be added. I personally do not use any DVD capabilities, so maybe a dvd USE flag may be appropriate.
