Built, should be on the mirrors soon.
Comment 3 Ralf Corsepius 2007-04-20 15:27:47 UTC 
The patch is very questionable:

Module: Kernel::System::Stats::GenerateGraph (v1.14.2.1) Line: 1171ff
read:

    foreach my $Module ('GD', 'GD::Graph', $GDBackend) {
        if (!$Self->{MainObject}->Require($Module)) {
            return $Self->{LayoutObject}->FatalError();
        }

I.e. At run-time, the package searches for perl(GD) and/or perl(GD::Graph) on
perl's default module search path and not for the package perl-GDGraph.

=> the rpm-correctly way would be to 
Requires: perl(GD) perl(GD::Graph)

and not to "Requires: perl-GDGraph"

perl(...) is the rpm-notation referring to the perl-module. perl-... is the rpm
notation to refer to the package. The difference between both become apparent
when perl modules move between packages (rather unlikely in this case).
