Problem with mailgraph-0.19

[Terry_22]

Hi all,
I've trying to get mailgraph running on a HPUX 10.20 box for monitoring Postfix traffic but hit snag when trying the command "perl mailgraph.pl -l /var/adm/syslog/mail.log" and the error is:

Can't load '/opt/perl5/lib/5.6.1/PA-RISC1.1/RRDs.sl' for module RRDs: No such file or directory at /opt/perl5/lib/5.6.1/PA-RISC1.1/DynaLoader.pm lin 206. at mailgraph.pl line 183. Compilation failed in require at mailgraph.pl line 183. BEGIN failed--compilation aborted at mailgraph.pl line 183.

I've installed rrdtool-1.0.33.depot from RRDTOOL website itself.

Any one has similar problems who can help?? I need to install this software to perform some mail monitoring.

Thanks a million,
Terry
