emerge stopped in the install-phase something like Kodi Send/kodi-send.py didn't exist. I changed the line in the ebuild in src_install so that it reads python_newscript "tools/EventClients/Clients/KodiSend/kodi-send.py" kodi -send after that the ebuild installs fine. apparently the name of the directory has changed. Because this is only a minor correction I've not submitted a emerge-log and the likes.
Forgot to check. It was already corrected.
