Problem with rtp/multicast

[Arijit Mukherji <arijit@cs.ucdavis.edu>]

Hi all,
	I recently got ns-2.1b3 and this is my problem. It compiles and
installs successfully, but won't run the simple-rtp.tcl script in 
~ns/ns-2/tcl/ex/simple-rtp.tcl.  It gives some error like the one below.
So I installed the 2 patches (in the ns problems web page) (first the one 
for intServ, then the one for multicast). now I have another problem. This
time i get a segmentation fault. the message is also included below. 

OK, i tried this on 2 platforms with exactly the same results, 
- solaris 2.6 on a sparc 5
- redhat 5.0 (linux kernel 2.xx) 

ns-2.1a3 did NOT have this problem but unfortunately i can't find the
ns-2.1a3 distribution at the ns website anymore :-(

any help would really be appreciated.

Thanks in advance !

Arijit
