Got my hands dirty and broke my leg (compiling qt-copy)

["J. Woch" <woch@gmx.de>]

Hi folks,

in a pathetic attempt to be useful in some way I decided to dig into KDE 
development. So I broke my leg at the very first step: compiling qt-copy :-)
Doing exactly what README.qt-copy told me, I'm getting this on 
Debian/unstable:

Since I'm new to nearly everything regarding KDE except using it for 
years, I'm neither able to determine how to isolate the flaw nor where 
to read for further instructions.
Any hints?

Ciao,
