I use Cacko 1.23 on a C3100
If you are using zbedic_1.1-0_arm.ipk, it has a "depends"
(This is a required software or library to enable zbdict to run).

------------------------------------------------------------------
Depends: sqlite3 library
Install sqlite3_3.2.2_arm.ipk if it is not already installed
------------------------------------------------------------------

I use English, so I'm using the following:
zbedic-English dictionary_0.9.0-1_any.ipk
