multicast error

[Hugh Smith <smithh@cse.msu.edu>]

I to am getting the same error when I run some of the multicast
examples. (I am using ns version 2.1b3.) Specifically the
simulations: tcl/ex/test-rlm.tcl, tcl/ex/mcast.tcl, and
tcl/ex/newmcast/mcast1.tcl (and 2 and 3).  The error seems to be
coming from the file: tcl/mcast/ns-mcast.tcl.  Has anyone found a
solution to this problem?

Thanks, Hugh
