Rtstats.pl: unknown method "plot_to_png"


I tried to use rtstats.pl, but when i want to execute it, it says "Can’t
locate object method “plot_to_png” via package “GD::Graph::linespoints”.

I have installed the newest versions of Chart, Chart::PNGraph, GD and
GD::Graph. Perl is version 5.6.0.

Any ideas about where could be the problem?
