Thats how fink works. the "libpng" and "libpng3" packages contain the 
headers, and the symbolic link to the appropriate version of libpng. 
the "libpng-shlibs" and "libpng3-shlibs" packages contain the actual 
libraries themselves. When a package wants to compile against the 3 
version, libpng3 is installed and the package links against that 
version.

IIRC the two are actually source compatible, so all packages should get 
updated to use libpng3 eventually...
