Comment(by cal@…):

 From the looks of your `config.log`, `pkg-config --exists --print-errors
 "libpng15 zlib"` doesn't signal any problems, so the configure script
 assumes you have libpng15 installed.

 Please provide the output of `pkg-config --cflags --libs --print-errors
 libpng15`, please search your system for any installed files named
 `libpng15.pc` and attach them.
