Welcome to the world of Cooker! What you actually have to do in the case of the libpng2 -> libpng3 shift (and many other major library upgrades, too), is to rebuild *all* of the libpng2-dependent apps against the new libraries. Often, this can be accomplished by simply downloading the src.rpm and issuing an rpm -bb command, but it can get a lot trickier.... hth -- john in syd
