I just set up a repo with Plasma 5, if someone feels so brave to test, read on:
Add in /etc/entropy/repositories.conf.d the file entropy_plasma5 with the following content: [plasma5] desc = Plasma5 Sabayon repository repo=https://mirror.spike-pentesting.org/mirrors/spike/plasma5#bz2 enabled = true pkg = https://mirror.spike-pentesting.org/mirrors/spike/plasma5 Then as usual do an equo up and install the metapackage (equo i kde-plasma/plasma-meta). For network manager you have to install plasma-nm, for having all systray working correctly you need also dev-libs/sni-qt (available in sabayon-limbo now). Please keep in mind this is still in testing, for any reference: https://wiki.gentoo.org/wiki/KDE/Plasma_5_upgrade#Missing_systray_icons and https://wiki.gentoo.org/wiki/Project:KDE/Frameworks Cheers
