$vs->compare($packages->{$package->{$PACKAGE}}{$package->{$ARCH}}{$VERS},
                          $package->{$VERS}) < 0) {
                     $package->{$RELEASE} = $release;
                     $packages->{$package->{$PACKAGE}}{$package->{$ARCH}} = 
$package;
                 }

a comparison is absent when these versions are in different Packages
files. I've attached a patch to add this comparison. Now, if I do
