The script is trying to make a link from a file to itself!
Which is obviously wrong. That's because you've set:
$trenddir = "/opt/trend/ISBASE/IScan.BASE";
but it's also in:
@linkdirs = ("/etc/iscan", "/opt/trend/ISBASE/IScan.BASE");

$trenddir is  the  'master'  directory  where  actual  files  will  be
downloaded to. The directories  in  @linkdirs  will  have  soft  links
pointing the the files in $trenddir maintained by the script.

OK, the comment describing @linkdirs isn't quite clear.
I'll improve it in a new version (suggestions for a better wording
are welcome).

Summary: change @linkdirs to:
@linkdirs = ("/etc/iscan");
