OK. Things are like this:
The package from debian http://packages.debian.org/sid/armel/kanjipad/download
has some extra dependency on libxinerama1 ... I don't know if it works.

The way I got it working was by downloading the debian src patch
and did that dpkg-buildpackage -rfakeroot thing.
The result didn't work in the scratch box but it works on the real tablet!
Here I attach the package that worked on my tablet.

One thing I need to confirm. It feels like my on my tablet it is more picky on how I draw the characters than on my desktop version (using mouse). Also tomoe recognised my writing better.
Is that because the dimensions of the window changed? Or I need more practice in drawing kanji? or I need to look for a better dictionary file somewhere?
