I'm attempting to optimize some legacy perl scripts written by a predecessor at my current job, and im getting some strange errors.
 
The script in question uses umask initially, and then executes a system command: 
umask(0002);
# ...lots of irrelevant code...
$val = `env VAR="blah" dbsearch`;

[download]
that command basically sets some environment vars (VAR, in the example) and then runs an executable (dbsearch, a home-made C program for a proprietary database)
 
when i run this script from the command line (as root) it runs fine, but when I run it through apache, it dies with "Insecure dependency in `` while running setuid at script.pl line 40"
 
i'm at a loss because i know next to nothing about setuid scripts (never had to use them), and would appreciate any help!
