Zhanam nieco podobne ako mailgraph

Pretoze ten sa mi na slacku nedari rozbehat vdaka hlaske:
./mailgraph.cgi
Can't locate RRDs.pm in @INC (@INC contains: /usr/lib/perl5/5.8.7/i486-linux /usr/lib/perl5/5.8.7 /usr/lib/perl5/site_perl/5.8.7/i486-linux /usr/lib/perl5/site_perl/5.8.7 /usr/lib/perl5/site_perl .) at ./mailgraph.cgi line 8.

Vygooglil som, ze blby rrdtool neinstaluje perl kniznice pri kompilacii tak som dal to, co pomohlo inym..make site-perl-install, ale mne to samozrejme nepomohlo;o).
Po rucnom prekopirovani do /usr/lib/perl5/5.8.7/ dostanem pre istotu:
Can't locate loadable object for module RRDs in @INC (@INC contains: /usr/lib/perl5/5.8.7/i486-linux /usr/lib/perl5/5.8.7 /usr/lib/perl5/site_perl/5.8.7/i486-linux /usr/lib/perl5/site_perl/5.8.7 /usr/lib/perl5/site_perl .) at ./mailgraph.cgi line 8
Compilation failed in require at ./mailgraph.cgi line 8.
