Comment(by trg818@…):

 Yes, it turns out that the include files of an old libpng15 installation
 were still there. I removed them, and openjpeg and ffmpeg now build
 correctly. Sorry for bothering.


 {{{
 ~> pkg-config --cflags --libs --print-errors libpng15
 Package libpng15 was not found in the pkg-config search path.
 Perhaps you should add the directory containing `libpng15.pc'
 to the PKG_CONFIG_PATH environment variable
 No package 'libpng15' found
 }}}

 {{{
