just joined the forum. and this thread is very old as well.
but would like to make a comment if some searcher can get this helpful.
you can schedule your script in cron to run every minute
and in your perl script check at the starting if another instance of script is running.
if so ...quit. else continue..
dont tell me that you need a code as well for this.. its pretty simple and wont take more then 3 lines..

CHECKSECURITY(8) System Manager's Manual CHECKSECURITY(8)
NAME
checksecurity - Run a collection of simple system checks
SYNOPSIS
checksecurity
DESCRIPTION
The checksecurity command runs a small collection of simple system checks which are designed to catch a few common security issues. check-
security is run by cron in a daily basis.
CONFIGURATION
The checksecurity.conf file defines several configuration variables: MAILTO, CHECK_DISKFREE, CHECK_PASSWD and CHECK_SETUID LOGDIR. Each is
described below.
The checksecurity program works with a collection of plugins which are located in /usr/share/checksecurity and are configured individually
by their own configuration file.
CHECK_PASSWD If this is set to TRUE then the check-passwd script will be invoked. This script is designed to report upon system accounts
which have no passwords. CHECK_DISKFREE If this is set to TRUE then the check-diskfree script will be invoked and will allow an alert to
be sent if there is any mounted partition is running short on disk space. CHECK_SETUID If this is set to TRUE then the check-setuid script
will be invoked, this will compare the setuid binaries upon the system to those that existed previously and show the differences.
FILES
/etc/checksecurity.conf
checksecurity configuration file
