Hi, 
After recompiling rrdtool 1.2.10 on aix 5.2 and hobbit 4.0.4, I have
infos in my rrd files (rrd fetch shows some entries). 
But I can't get any graph at the bottom of hobbit pages. 
I tried to run the cgi from command line, but I have the following
message : "xgetenv: Cannot find value for variable QUERY_STRING"

How can I set the QUERY_STRING properly and try to generate my graphs ? 
Thanks
