Bugzilla Bug 137027

Building gimp-2.2.10 or 2.2.11 against libpng-1.2.10 fails with the following
error (excatly the same error with the 2 releases):

png.o: In function `load_image':
png.c:(.text+0x815): undefined reference to `png_read_destroy'
png.o: In function `save_image':
png.c:(.text+0x17f2): undefined reference to `png_write_destroy'
collect2: ld returned 1 exit status

i already have problems with cups (png problems) and imagemagick(bug136452) on
install.
