Here is the summary of what I did to make it work:

download toMOTkoFremantle-r943
rename the file to toMOTko (you can do it in MC or in the default File Manager)

run the following commands (you need Midnight Commander installed, you can do it without MC but you need to know the basic linux bash commands: for example, sudo copy toMOTko /opt/maemo/usr/bin/toMOTko)
In MC, copy the new toMOTko file into the following folder: /opt/maemo/usr/bin/
Agree to replace the file that is already there.

then in X Terminal run,
Finally, add Maemo’s “extras-devel” repository (if it's not yet added)
and in X Terminal run,
Wait for it to finish (you need the internet connection for it to download the needed packages).

Voila, it should work.

P.S. Given that you already played with toMOTko files, maybe the first step would be to uninstall and then reinstall toMOTko to make sure that we are starting from the same point.
