Hotsanic ma problem s rrdtool

Chcel som si u seba doma rozchodit hotsanic. Ako prve som si instalol rrdtool (1.2.23). Potom som konfigurol hotsanic ale grafov nieto. Log hotsanicu mi oznamuje divne veci.
starting module: "apps"

atd.
Divne je to preto, ze som konpiloval rrd zo zdrojakov bez najmensej chybicky. Pritom tato chyba hlasi, ze v perle nie je ziadne rrd modul.
