[Q] gt-itm

Hello,

I tried to configure network topology by using gt-itm....

But, I got an error message following

    Creating links 0...-o4: unable to dispatch method duplex-link-of-interfaces
        while executing
    "$ns duplex-link-of-interfaces $n(0) $n(9) $linkBW 40ms DropTail"

I used "sgb2ns" which gives me tcl file for ns..
and there is "duplex-link-of-interfaces" method in the tcl file..

what should I do?? 

First, I replaced it with "duplex-link". 
As a result, I have no error message.. but, the result shown by nam is not correct..

Can anybody help me??
