Created attachment 499418 [details] libreoffice ebuild https://wiki.documentfoundation.org/ReleaseNotes/6.0 Alpha version of the upcoming release 6.0. libreoffice-l10n removed as it haven't published.
We don't usually add alpha releases to tree. Bug how about solving bug 609054, bug 629834 and bug 628138 instead, so that you can use the live ebuild and actually make a 6.x.x.x package work?
