Thanks for the link.
I have been looking this code and it seems that this .py works with the OS2005, into the OS2006 they changed some thing of python and the syntax is different in hildon module.

I say to port the new version 1.3 (http://lybniz2.sourceforge.net/) that already deletes the problem of ** and ^
Is a simple port and it will not go a lot of time, a couple of days as much.

Do not worry with the .desktop it's necessary to do a link to another file in order that it works. It will do automatically the package .deb

Sorry for my english, is too bad

Best Regards.
