[Bug: 21.5-b28] setting input-method to japanese-canna brings only No Canna API support!?

Setting xemacs via M-x set-input-method RET japanese-canna RET shows only the error "No Canna API support!?" See M-x describe-installation & C-h v module-load-path xemacs is compiled with the flag --with-canna and the canna-server is running (Anthy with canna functions w/out any problems).
