I support this procedure. The original versioning of the png
library is horribly broken. Just be sure to include conflicts to those
packages mentioned above with the version as shipped in bo.
The only problem is with telling dpkg that the new package really is an
upgrade, not a downgrade.
As one of the issues for hamm is the switch to libc6 and all of the
libraries have to be recompiled anyway it's no large problem with
having a different version number for the library.
