Package: libpng-dev Version: 1.5.6-1 With libpng-dev from experimental installed, the d-conf package (and probably many other gtk-using packages) will FTBFS with something like:

Perhaps you should add the directory containing `libpng12.pc' to the PKG_CONFIG_PATH environment variable Package 'libpng12', required by 'GdkPixbuf', not found 1 consoleuser@stylus:/tmp$ arguably, d-conf's ./configure script should also be failing if pkg-config --cflags gtk+-3.0 returns a non-zero error code (feel free to clone this bug and reassign the clone to d-conf if you see fit). libgdk-pixbuf2.0-dev seems to be the only package i have installed on this machine who mentions libpng12 (via Requires.private) in its pkg-config file, though libcairo2-dev refers to the bare libpng in cairo.pc's Requires.private, and in cairo-png.pc's Requires section. Maybe if Cairo can use the bare libpng here then it's save to use it in gdkpixbuf as well? or if gdkpixbuf is doing the right thing, maybe cairo's pkg-config files are too lax, potentially leading to a nasty multi-library linkage during the transition? I don't know enough about pkg-config or the inner workings of these tools to say; feel free to explain and reassign if you think this bug could be re-assigned to another package. Thanks for your work maintaining libpng in debian! I hope we can make the transition to 1.5 soon.
