Tried to emerge the kde3 package.
Did emerge rsync, it updated my portage dir, got the all new kde-3.0.ebuild file.
So i tried to merge the KDE3 window manager.
Got ERROR : !!! ebuild kde-base/kde-3.0 not found (possibly blocked by package.mask)
Wel indeed, checked it out and this dir does not exist.
This is what DRobbins writes in /usr/portage/profiles/package.mask:
# committed to facilitate testing by several devs, mostly Verwilst and me.
# testing should be over in 24h so don't unmask without good reason.
# added kdeadmin, kdeaddons as well // Spider
ps. There shouldn't be a kde-3.0 dir, it is kde-base/kde/kde-3.0.ebuild
