ToME 2.3.5 was relased a few days ago. It now has support for 64bit systems, a updated GTK2 interface and many bugfixes. I modified the current ebuild found in portage to support GTK+2 instead of GTK+1 and defines to build in AMD64. I only tested it in AMD64.

Version 2.3.5 is now in portage. Thanks
