Error when executing Cacti poller.php

Question

I have installed Cacti, and when I run poller.php, it gives me following error:

sh: /rrdtool: No such file or directory

I have tracked it to the following bit of code:

$command = '/usr/bin/rrdtool' . " - ";

$rrd_struc["fd"] = popen($command, "w");

what could be the problem here?

If anyone stumbles upon this, check if your safe_mode is turned off.
