clamav

I am installing a qmail server last few days i faced poblem
with clam permission, after reading I figure out the problem, clam was
running as root I change owner id to qscan
[root@mail init.d]# ps -aux | grep clam
qscand 2244 0.0 0.7 9264 8088 ? S 19:58 0:00 [clamd]
root 2246 0.0 0.0 3748 556 pts/2 S 19:58 0:00 grep
clam

I resolved the issue with the permission,
now i have the problem
"Undefined subroutine &main::minidebug ..."
