./test-all-mcast --> run-mcast error.

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

  I have installed ns-2 two days ago.
  I have patched all needed.

  I wanted to test a mcast example ( ~/ns-2/tcl/test/test-all-mcast) and

  executed that file.

  But several same errors occured.
  -->
       ns: _o4 run-mcast : invalid commnad name "0"
            while executing
       "[$link set ifacein_] set intf_label_"
             (procedure "_o33" line 3)
             (Node get-oif line 3)
             invoked from within
       "$self get-oif $link"
             (procedure "_o33" line 5)
             (Node init-outLink line 5)
             invoked from within
       "$node init-outLink"
             (procedure "_o4" line 5)
             (Simulator run-mcast line 5)
             invoked from within
       "_o4 run-mcast"
------

   I want to know what's the problem.

   I am a graduated student at CS dept. of Dongguk Univ. in Republic of
Korea.
