There is a new RC for xdg-utils with support for KF5, would be nice to have it upstream in Gentoo Reproducible: Always
There have been further commits in git, which look worthy to add. http://cgit.freedesktop.org/xdg/xdg-utils/
Small adjustments to the old ebuild (SRC_URI to exclude the patchset + src_prepare to not use the patchset but the git diff that includes the latest changes) and everything went fine. I did not check if features/options were added/changed/removed. KDE5-Support works fine.
yeah I am using it for months no and it solved all my xdg problems since then. This should be really get upstream before plasma5 gets.
