I am getting the same error on my build as well. It fails as previously described at linking with undefined references. Additionally, I tried downgrading my libpng to 1.2.10 and got no love there either. I tried linking tuxpaint against both versions of libpng with varing undefined references. # emerge -v tuxpaint >>> Compiling source in /var/tmp/portage/tuxpaint-0.9.15b-r1/work/tuxpaint-0.9.15b ... ...Compiling Tux Paint from source... src/tuxpaint.c:165:1: warning: "__USE_GNU" redefined In file included from /usr/include/stdio.h:28, from src/tuxpaint.c:163: /usr/include/features.h:270:1: warning: this is the location of the previous definition src/tuxpaint.c:428:1: warning: "likely" redefined In file included from /usr/include/asm/sigcontext.h:4, from /usr/include/bits/sigcontext.h:28, from /usr/include/signal.h:333, from src/tuxpaint.c:202: /usr/include/linux/compiler.h:73:1: warning: this is the location of the previous definition src/tuxpaint.c:429:1: warning: "unlikely" redefined /usr/include/linux/compiler.h:74:1: warning: this is the location of the previous definition src/tuxpaint.c:2547:2: warning: #warning Benchmark times are based on a 450 MHz CPU. src/tuxpaint.c: In function 'do_shape': src/tuxpaint.c:12824: warning: unused variable 'tmp' ...Linking Tux Paint... obj/tuxpaint.o: In function `do_png_save': tuxpaint.c:(.text+0x4e33): undefined reference to `png_create_write_struct' tuxpaint.c:(.text+0x4e46): undefined reference to `png_create_info_struct' tuxpaint.c:(.text+0x4e76): undefined reference to `png_init_io' tuxpaint.c:(.text+0x4eba): undefined reference to `png_set_sRGB_gAMA_and_cHRM' tuxpaint.c:(.text+0x4ef0): undefined reference to `png_set_text' tuxpaint.c:(.text+0x4f02): undefined reference to `png_write_info' tuxpaint.c:(.text+0x4fbb): undefined reference to `png_write_image' tuxpaint.c:(.text+0x5001): undefined reference to `png_write_end' tuxpaint.c:(.text+0x5013): undefined reference to `png_destroy_write_struct' tuxpaint.c:(.text+0x5049): undefined reference to `png_destroy_write_struct' tuxpaint.c:(.text+0x50aa): undefined reference to `png_destroy_write_struct' tuxpaint.c:(.text+0x50d1): undefined reference to `png_destroy_write_struct' collect2: ld returned 1 exit status make: *** [tuxpaint] Error 1 !!!

Thanks for reporting this issue. This has been fixed in the tree, please re-sync in an hour or two and try again.
That works now, on both platforms, thanks!
Yep, compiles and links fine now. Thanks for the support.
