Hello,
They have done something in this release that is not going to sit well for
us with regards to only using stable releases for things.
They have changed to using the latest version of png, namely 1.6.14beta01.
I cannot confirm this. kdelibs builds fine for me.
How do I know this?
Well when compiling it I got the following error 79% into the build:

$ grep PNG_READ_BGR_SUPPORTED -r *
libpng16/pnglibconf.h:#define PNG_READ_BGR_SUPPORTED
libpng16/png.h:#if defined(PNG_READ_BGR_SUPPORTED) ||
defined(PNG_WRITE_BGR_SUPPORTED)
png.h:#if defined(PNG_READ_BGR_SUPPORTED) ||
defined(PNG_WRITE_BGR_SUPPORTED)
pnglibconf.h:#define PNG_READ_BGR_SUPPORTED
So that's defined in libpng16/pnglibconf.h and pnglibconf.h.
I think you may be missing a dependency, but I can't tell which one.
