[ns] GPRS simulation problem

["Jeff Di Costanzo" <metrojeff@hotmail.com>]

Hi everyone,
has anybody applied the GPRS module patch contributed by Richa Jain to
ns2.1b7a and experienced problems running all/some of the wireless example 
tcl scripts such as simple-wireless.tcl?....
the error i'm getting looks something like...

[jeff@localhost ex]$ ns simple-wireless.tcl
warning: Please use -channel as shown in tcl/ex/wireless-mitf.tcl
can't read "rlcType_": no such variable
    while executing
"$node add-interface $chan $propInstance_ $llType_ $rlcType_ $macType_
$ifqType_ $ifqlen_ $phyType_ $antType_ "
    (procedure "_o3" line 50)
    (Simulator create-wireless-node line 50)
    invoked from within
"_o3 create-wireless-node"
    ("eval" body line 1)
    invoked from within
"eval $self create-wireless-node $args"
    (procedure "_o3" line 14)
    (Simulator node line 14)
    invoked from within
"$ns_ node"
    ("for" body line 2)
    invoked from within
"for {set i 0} {$i < $val(nn) } {incr i} {
                set node_($i) [$ns_ node]
                $node_($i) random-motion 0              ;# disable random 
motion        }"
    (file "simple-wireless.tcl" line 93)

-------------------end

thanks in advance,
jeff
