Jens Rasmussen (firstname.lastname@example.org) has contributed a working version of tkdic with these comments:
" would like to contribute some (hopefully useful) information. At the end of this mail I attached a uuencoded version of tkjdic which compiles on my system. Maybe your problem is that tkjdic-0.9 is written for tk3.6. The actual version is tk4.0 (e.g. included in Japanese Extensions 0.9.6 and above) and they are incompatibile."
