ask for ns2mesh80216

[Tu Tran]

I have installed NS2-2.33.The installation completed sucessfully, and I set the PATH, LD_LIBRARY_PATH,
& TCL_LIBRARY variables as per the install message. And I have installed the patch ns2mesh80216 from http://cng1.iet.unipi.it/wiki/index.php/Ns2mesh80216
However when I run the mesh.tcl (/ns-allinone-2.33/ns-2.33/wimax/tcl/mesh.tcl) ,
 I get the following errors.
(_o4 cmd line 1)
    invoked from within
"_o4 cmd run-identifier 1"
    invoked from within
"catch "$self cmd $args" ret"
    invoked from within
"if [catch "$self cmd $args" ret] {
set cls [$self info class]
global errorInfo
set savedInfo $errorInfo
error "error when calling class $cls: $args" $..."
    (procedure "_o4" line 2)
   
 (SplitObject unknown line 2)
    invoked from within
"$ns run-identifier $opt(run)"
    (procedure "init" line 9)
    invoked from within
"init"
    (file "mesh.tcl" line 306)


I will be very grateful if you could help me overcome this problem.
