Is this OK or do you have any suggestion >> how to improve the dependencies

I cannot help, sorry. I am just a normal user and not familiar with debians package dependency system. For the meantime its perfectly ok with me. Also i have to say that i quickly found out the missing package with a apt-cache search. I guess for an advanced lisper, which i am not (yet), the issue can be handled easily. -- "Ein Herz für Kinder" - Ihre Spende hilft!
