We need to update all current ebuilds that use the combined dev-lang/tcl-tk
ebuild to use the new split tcl/tk ebuilds. According to my search of the
portage tree, there are 23 individual ebuilds with many duplicates for different
vers of the same program.
Since I just invalidated bug 102, I think this one can be closed also. I'll
leave it up to your discretion, though.
