Hi! Sorry for my English. There is a bug in kde-base/kdepim-l10n: the kde-base/kde-l10n ebuild filtered out subdirectories kdepim-runtime and kdepim, but kde-base/kdepim-l10n ebuild included kdepim subdirectory only. As result many i18n files inaccessible from kdepim-runtime subdirectory. Please, fix kde-base/kdepim-l10n ebuild - add kdepim-runtime subdirectory. The bug exists for versions 4.7.3 and 4.7.4 Regards.
