question on wireless network simulation

[Jong-seon Kim <jkim@rcf-fs.usc.edu>]

Hi,

I have installed ver. 2.1b5 and daily snapshot for ns-2 and 
tclcl, and run the example tcl code from tutorial.
In the mean time, the error msg is like this:

>ns simple-wireless.tcl
invalid command name "create-god"
    while executing
"create-god $val(nn)"
    (file "simple-wireless.tcl" line 69)

>ns wireless1.tcl
_o3: unable to dispatch method namtrace-all-wireless
    while executing
"$ns_ namtrace-all-wireless $namtrace $val(x) $val(y)"
    (file "wireless1.tcl" line 77)

What is the problem?

Thanks,

Jong-Seon
