Hm, mal schauen.

Habe nochmal komplett aufgeräumt und in einem leeren Verzeichnis neu
angefangen.

$ git clone https://github.com/volkszaehler/vzlogger.git

$ ./configure --disable-sml --enable-debug

$ make

Und nun - nach vielen Versuchen mit checkinstall, wo immer die
debug-symbols auf der Strecke blieben - das binary auf den Server kopiert.
