run time error in "run-mcast".

[Chango Cho <compusm@chollian.dacom.co.kr>]

I am going to test the correct installation of ns-2 in Solaris 2.5.1.
(SUN sparc)

I executed ~/ns-2/tcl/ex/simple-rtp.tcl using ns.
Then Some errors were occured.
Those are like this

    ns: _o3 run-mcast: invalid command name "0"
         while executing
    "[$link set ifacein_] set intf_label_"
          (procedure "_o10" line 3)
          (Node get-oif line 3)
          invoked from within
    "$self get-oif $link"
          (procedure "_o10" line 5)
          (Node init-outLink line 5)
          invoked from within
    "$node init-outLink"
          (procedur "_o3" line 5)
          (Simulator run-mcast line 5)
          invoked from within
    "_o3 run-mcast"

I patched all needed.
I want what the problems are.
Please answer me.
