LinuxQuestions.org - Error when adding LAR to ns2

I just install ns2.32
and patch the lar patch file with all the required changes as discriped in http://wing.nitk.ac.in/resources/Imp...0in%20NS-2.pdf

but i have this problem

invalid command name "Agent/LAR"
while executing
"Agent/LAR create _o815 "
invoked from within
"catch "$className create $o $args" msg"
invoked from within
"if [catch "$className create $o $args" msg] {
if [string match "__FAILED_SHADOW_OBJECT_" $msg] {
delete $o
return ""
}
global errorInfo
error "class $..."
(procedure "new" line 3)
invoked from within
"new Agent/LAR"
("for" body line 2)
invoked from within
"for {set i 0} {$i < $val(nn)} {incr i} {
set g($i) [new Agent/LAR]
$node_($i) attach $g($i) 254

# need to tell the lar agents about their link ..."
(file "box.tcl" line 174)

That mean it cannot see the LAR protocol
