(This is Fedora Core release 4 (Stentz))
         libpng12.so.0 -> libpng12.so.0.1.2.8
         libpng.so.2 -> libpng10.so
         libpng12.so.0 -> libpng12.so.0.1.2.8

[igg at lgopt5 ~]$ rpm -qa | grep png
libpng-1.2.8-2
libpng10-devel-1.0.18-2
libpng-devel-1.2.8-2
libpng10-1.0.18-2
libpng-1.2.8-2


What distribution/package manager are you using?
