Ok I see what has happened now. The libpng2/3 fiasco continues.
It appears that after having to recompile kmerlin to work with libqt2/libpng3 that they (maintainers of those pacakages) have decided that I again have to recompile, but this time with libqt2/libpng2. :-( I'll upload something in the next couple of days. If you are really desperate an `apt-get build-dep && apt-get source -b kmerlin` will build your own kmerlin package for you which is usable. Mark
