Version 0.67.0 of the qtcurve theme is available. I'd like to see it in portage as I expect it to fix bug #276735. The following packages should be made available: x11-themes/qtcurve-qt4-0.67.0 x11-themes/qtcurve-0.67.0 x11-themes/gtk-engines-qtcurve-0.67.0 Haven't tried yet whether they work out of the box by simply copying existing ebuilds or whether some additional work is required.
These have been committed.
