QtCurve has recently switched hosting locations to the KDE infrastructure. The new repo URLs are: read-only: git://anongit.kde.org/qtcurve
commit 007835f10f1c35e9da072186b5fca6f20560eb3d Author: Lars Wendler <polynomial-c@gentoo.org> Date: Fri Nov 11 21:06:40 2016 x11-themes/qtcurve: Added live ebuild based on work from seden overlay. Package-Manager: portage-2.3.2 The new live ebuild reflects that. I don't think the release ebuild needs this change as the new upstream did not do any releases yet.
Release version 1.9.0_rc1-r1 points to KDE infrastructure now.
