Question on mac-test.tcl

["Laura-Lei Liu" <liul@nortelnetworks.com>]

hello,

When I run under ns-2/tcl/ex/

# mac-test.tcl -node 4 -stop 400
../..
_o18: unable to dispatch method trace
    while executing
"$lan trace $ns $trfd "
    (file "./mac-test.tcl" line 160)

What does the error message mean?

If I source two files ns-2/tcl/lan/ns-lan.tcl and ns-2/tcl/lan/ns-mac.tcl
into the mac-test.tcl, the above error will disappear. But I got another
error message:

Number found where operator expected at (eval 3) line 1, near "6 2"
(Missing operator before 2?)

Where should I look for the problem? 

Thanks for the help!
