Did you try setting PNG_CFLAGS / PNG_LIBS or using sed, as the message
I quoted suggests ? I think sed would definitely prevent kate from
using libpng14 (or libpng12 if you want to force the use of libpng14).
But I'm not sure the libpng versions are really the problem, since you
said that without using kdesu there is no issue. Did you try running
Kate both with commandline sudo, su and su - ? If the results are not
the same, there are problems with environment variables.
