WiMax QoS example problem in ns2

Hi. I have installed wimax module from on ns-2.29-3 in fedora15 successfully.

But when I run the examples provided in tcl/wimax directory (8MN_datarate.tcl and QoS_example1.tcl) I get the followint error:

[n@localhost wimax]$ ns QoS_example1.tcl 8MN_datarate.tcl OFDM_BPSK_1_2 0.25
Configuration of hierarchical addressing done
num_nodes is set 30
sink node created

(_o54 cmd line 1)
invoked from within
"_o54 cmd set-default-modulation 8MN_datarate.tcl"
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" $..."
(procedure "_o54" line 2)
(SplitObject unknown line 2)
invoked from within
"$bs_sched set-default-modulation [lindex $argv 0] "
(file "QoS_example1.tcl" line 121)

Anyone has faced this problem before? how to solve it?
Please help.


ns2, wimax
