I am guessing (with all my vast linux experience...that's sarcasm) that
perhaps the send_mail.pl wrapper does not know how to find the actual
senmail file which is located in /usr/lib.  I don't see anything in the
send_mail.pl script that indicates it is looking for it though.  Here is
the send_mail.pl file contents:

#!/usr/bin/pearl -w
#
# Wriiten by Rob Moss, 2005-10-09
# coding at mossko.com
#
# A replacement for Nagios's basic mail system which relies
on /bin/mailx and local sendmail config
#
# To use this, just replace the entries in commands.cfg and update your
hosts and services from the default "notify-by-email" to use the
specific host-notify-by-email or service-notify-by-email
#
# I put this in the plugins directory /usr/local/nagios/libexec but you
can put it anywhere. Just update the path

# commands.cfg
#define command{
#	command_name	host-notify-by-email
#	command_line	$USER1$/send_mail.pl -n "HOST $NOTIFICATIONTYPE$" -h
"$HOSTNAME$"  -s "$HOSTSTATE$" -a "$HOSTADDRESS$" -i "$HOSTOUTPUT$" -d
"$LONGDATETIME$" -e "$CONTACTEMAIL$"
#}
#
#define command{
#	command_name	service-notify-by-email
#	command_line	$USER1$/send_mail.pl -n "SERVICE $NOTIFICATIONTYPE$" -h
"$HOSTNAME$" -s "$SERVICESTATE$" -a "$HOSTADDRESS$" -i "$SERVICEDESC$ -
$SERVICEOUTPUT$ - $SERVICECHECKCOMMAND$" -d "$LONGDATETIME$" -e
"$CONTACTEMAIL$"
#}

# contacts.cfg
#define contact{
#	contact_name					nagiosadmin
#	host_notification_commands		host-notify-by-email
#	service_notification_commands	service-notify-by-email
#	email							email at address.com
