libpng-1.2.12 has been rapidly stabilized due to a buffer overflow in 
<libpng-1.2.12 [1]. A lot of packages in stable that depend on libpng are 
incompatible with libpng-1.2.12. In most if not all cases a newer version 
that is compatible exist in ~arch but it has not yet been stabilized. A 
tracker bug [2] has been created to get those packages that are compatible 
with libpng-1.2.12 rapidly stabilized but it probably will take some time.

Therefore the best solution seems to be to stick with libpng-1.2.12 and run 
`emerge -vtpDu world` to see which packages are pulling in the old version of 
libpng. In most cases there should be a newer version that needs the ~arch 
keyword in /etc/portage/package.keywords in order to be installed and thereby 
stop pulling in the old version of libpng. If you need help post the output 
of `emerge -vtpDu world` where it is trying to downgrade libpng...
