they appear to be the same pkg ... i'd suggest punting Tk_Theme
As far as I remember, they are not the same thing. One of the ebuilds grabs a tarball from http://www.xmission.com/~georgeps/Tk_Theme/, while the other --- from http://www.xmission.com/~georgeps/Tk_Theme/other/ . It may well be that the two things are essensially the same, but they do install different files (again, as far as I remember). I thought that I needed Tk_Theme for net-im/tkabber, but then figured out that I really needed tkTheme instead. I ended up not using Tk_Theme; I don't mind dumping it from the portage tree, but since I wrote the ebuild, why not keep it in the portage tree, in case somebody else needs it in the future?.. I am not sure.
i didnt know if they were indeed the same pkg which is why i asked you to look at em ... if they arent, then just leave em :)
Closing the bug, then.
