Gnome 2 is unsupported, and in a few days it will be masked for removal, see bug #508854. If you want a desktop environment that feels like Gnome 2, your options are Gnome 3 in classic mode, XFCE, or MATE. See http://blogs.gentoo.org/eva/2014/02/16/the-future-of-gnome-2/ for the explanation.
I guess LXDE to be removed any soon as well ;-) Thks for your reply.
Removal of Gnome 2 has no relation to LXDE. We will not remove components that are still used by other desktops. However, we will most likely transfer maintainership if such packages are not used by Gnome anymore.
