[ns] validation problem

["hjj" <huang008@ms6.hinet.net>]

Hi,

I am a newer for ns.
Recently, I installed the ns-2.1b8 on the RedHat 7.2 platform.
After I ran the validation, 20 tests or so did not pass.
Those include: ./test-all-(tcp, testReno, newreno, sack, tcpOptions,
tcpReset, tcp-init-win, tcpVariants,
                         aimd, rfc793edu, rfc2581, ecn, ecn-ack, ..., and so
on).

Then, I entered into ~/ns/tcl/test and ran test-all-tcp, the messages at the
end of this mail showed up.
In fact, most failed tests have almost same message like this.
I also ran diff for ecn amd ecn.test ( diff ecn ecn.test), and find out that
ecn.test contains almost nothing,
see attached files, please. (what does it really means when nothing was
there?)
According to some discussions made on the previous ns-users mailing list
archieves, the problem seems
to be due to an old version Perl installation. However, the Perl that I
installed downloads from the current ns
website and it should be a newer version (I think).

What is the possible reason for these validation failures? Should it be the
Perl's problem, how can I fix it?

Thank you for seeing my problem.

Test output differs from reference output.
