Subject: [smokeping-users] no graphs?

Hello all, I'm a somewhat knowledgeable linux person, but I have pushed beyond my boundries with the CGI component here.

I have smokeping running, and it appears to be collecting data in /tmp /smokeping-ms/data/Test/, but it doesn't appear to be creating the graphs.

When I navigate to http://sitename/cgi-bin/smokeping.cgi?target=Test I get:

I can see that it's probably a permissions thing, but whom do I give permission to what?
