[ns] Traffic Trace with prebuilt win 32 binary

I downloaded the ns-2.1b5.exe win32 binary, just to ensure that I hadn't flubbed anything in my build process. Then I took the "example-trace" file that is included in the source distribution, that is used in the tg.tcl example, and put it into the same directory. Then I run the following script, and I still get the same message "warning: no class variable Tracefile::debug_", and the trace output is empty.

ANY help would be greatly appreciated.

set ns [new Simulator]
set n0 [$ns node]; set n1 [$ns node]
set endtime 1.0
$ns duplex-link $n0 $n1 100.0M 2ms DropTail
set null0 [new Agent/Null]
$ns attach-agent $n1 $null0
set s [new Agent/UDP]
$ns attach-agent $n0 $s
set tfile [new Tracefile]
$tfile filename dumpster
set tr [new Application/Traffic/Trace]
$tr attach-tracefile $tfile
$tr attach-agent $s
$ns connect $s $null0
$ns at 0.0 "$tr start"

set flow [open tuttrace.out w]
$ns trace-queue $n0 $n1 $flow

$ns at [expr $endtime + .01] "finish"
proc finish {} {
global ns flow
close $flow; $ns flush-trace
exit 0
}
$ns run

Trying to run the following condensed version of tg.tcl in ns/tcl/ex. I get a "warning: no class variable Tracefile::debug_"

Any ideas? If I take the original tg.tcl script, and remove the lines for the tracefile driven source, it works fine, as has everything else up until now.

Thanks very much,

Peter.
