You may also need "wget" for zmapper to work. I think I forgot the dependency. Another red-pill only. (use dpkg and/or apt-get on the libqt and for wget).

(as root "apt-get install wget")

And create on the internal and/or external cards a "zmap" directory. Otherwise it will store things to /usr/lib/zmap and it can get full, but you can copy the state directories to the external cards.
