OK, thanks to eveyones help I got this going.  The problem turned out to be the single quotes embeded in a double quoted string.  I changed them to escaped double quotes and all was well. New version is:

# Manage the backlight. If lid is open, turn the screen and kscreensaver on.
# If the lid is closed, turn off screen and kscreensaver.  This allows the
# laptop to be docked with the screen and kscreensaver off while connected
# via a metaVNC session to my desktop machine.  If one were using an external
# monitor with the docking station instead of a vnc connection turning off the
# screensaver probably not be desireable.
# Operation: su is used to call perl_dcop.pl.  This is nessecary as perl_dcop
# calls a kdesktop dcop interface to control the screensaver and dcop must be
# from the user whose applications you are trying to interface with.  The
# escaped double quotes \" were needed so perl would pass the entire argument
# to the system. 
if ($will_sleep==0 && $device eq "LID") {
 	if ($lid_state eq "open") { # reopening.
		backlight "on";
		system "su birtj -c \"/etc/acpi/actions/perl_dcop.pl true\" ";
	} elsif ($lid_state eq "closed") { #closing.
		backlight "off";
		system "su birtj -c \"/etc/acpi/actions/perl_dcop.pl false\" ";
	}
}

Thanks again!
