RSVP/ns - please help ...
For some time I have been trying to install RSVP/ns software
(http://titan.cs.uni-bonn.de/~greis/rsvpns/) on top of the network
simulator version ns-2.1b3 . (I have already given up my earlier trying to
involve
version ns-2.1b4.) My OS is Red Hat Linux 5.2, kernel 2.0.36, on i686
based PC.
My attempts have been only partially sucessful. Whereas the installation
itself did
not generate any complaints, of the four examples that are part of the
RSVP/ns package,
only one worked - the rsvp_conf.tcl. The other three - rsvp_merge.tcl,
rsvp_distinct.tcl,
and rsvp_large.tcl - did not.
To try to see what was involved, I used the GNU debugger. I include below
the results.
I have not a clue as to what the trouble is. I do not know whether anyone
has ever
managed to run the RSVP/ns on Linux. I do not know even on which OS has
the RSVP/ns
software been actually running.
If anyone on the list could provide some help, or at least some hints how
to resolve the problem, it would be much appreciated.

rsvp_merge.tcl
Attempts to run the RSVP/ns package example rsvp_merge.tcl (which is
located in my /usr/src/NS/ns-allinone-2.1b3/rsvp/tcl/ex/rsvp directory)
failed (saying "Segmentation fault", and generating empty trace and nam
files), so I turned on the GNU Debugger and got the following:

The file
