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 :-) Peter -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
