Just a heads up. I had to fix the imlib, imlib2 and imagemagick
packages that were initially put in the jpng repo.  There was
undefined symbols in the libraries. I believe it only affects when you
try to link the library.  So packages that were successfully built
against the broken libs are probably OK. I haven't tested though.

BTW, when trying to rebuild xfig and transfig, I'm getting this error:

dev/libtransfig.a(readpng.o): In function `read_png':
readpng.c:(.text+0x6a2): undefined reference to `png_set_dither'
collect2: ld returned 1 exit status
make[1]: *** [fig2dev] Error 1

I didn't find any mention about png_set_dither in the libpng 1.4.0
docs. Did another rebuilder encountered this problem? Does anyone know
how to fix it? For the time being, I'll skip it.

Another problem: Even after patching for libpng, xine-ui doesn't work.
The window appears for a second then prints bunch of error messages
like :

IMLIB ERROR: Cannot load image: /usr/share/xine/skins/xine_splash.png
All fallbacks failed.
xiTK WARNING(xitk_image_load_image:1646): xitk_image_load_image():
couldn't find image /usr/share/xine/skins/xine_splash.png
IMLIB ERROR: Cannot load image: /usr/share/xine/skins/xinetic/MainBg.png
All fallbacks failed.

I'll also skip it for now. If anyone has an idea on how to fix it or
wants to work on  it, go ahead.
