skktools binary package in Ubuntu Xenial arm64

 This package provides tools to maintain dictionary files for SKK
 Japanese input systems.

 SKK dictionary files are provided by the skkdic package and the
 skkdic-extra package. You can make a local dictionary file from
 them.
 .
 If you want to convert a dictionary file to cdb (DJB's constant
 database), install the tinycdb package. To use the optional scripts,
 install the required tools, such as gawk, ruby, gauche, etc.
