The problem is that a lot of the core packages in the build root
depend on libpng so you can't bump the soname without having the
compat one around because you can't rebuild a whole bunch of packages
that need to be installed to rebuild them so you end up in a chicken
and egg senario.... bump libpng soname ...... can't install build
chain to rebuild other packages because a required soname dependency
has disappeared :-)
