Sorry but this is based on QTcurve engine and cannot be used directly with the real equinox. Though I think you can use it in GNOME through a trick. __ Install systemsettings package. It will pull a lot of KDE dpendencies. __ Install Qtcurve( both kde and gtk engines) __ Open systemsettings, go to appearance, select QTcurve in the dropdown. Click configure and a dialog will open. Click Import and select the QTcurve file and click OK then Apply. __In the GNOME appearance properties, select QTcurve as the theme.
I hope this helps. Though I've not really tested it, but I think it should work..
