error message "Random is not portable"

[Mikihiro Ueno <ueno@cis.ohio-state.edu>]

Hi there.

I just started learnig ns. Let me ask a basic question.
I installed ns-allinone-2.1b5 and it was successful.
But following the tutrial (http://titan.cs.uni-bonn.de/~greis/ns/ns.html),
I run ns with the file "example1a.tcl" which includes only two nodes and one link,
and I got an error message;

        % random() called in ns.
        Random is not portable, please use Random::uniform() instead.

and nam won't be started automatically.

What's wrong???

can anyone help me this problem?



Thanks in advance
