Welcome to LQ.

Any particular reason to use the old ns-2.30 ?
The latest version is 2.34 , works OK on Fedora 9.

I never saw the error, you have.
How did ./validate turn out ?

Is it all tcl sripts, causing that error ?
Please try with some of the 300 scripts in ns-2.30/tcl/

Or use some of the examples e.g.
http://nile.wpi.edu/NS/simple_ns.html
from http://nile.wpi.edu/NS/

Or .. http://www.isi.edu/nsnam/ns/tutorial/
http://www.isi.edu/nsnam/ns/tutorial/nsscript1.html
http://www.isi.edu/nsnam/ns/tutorial.../example1b.tcl
etc. etc.

This is not an error in actual, but this is a wrong attempt to execute your script file like following way.
Running script like this is not allowed , I mean it will generate the error ( $ ns

% ns examplename.tcl <~~~~ Please DON'T go like this )

Please run your script like this way.

$ ns examplename.tcl <~~~~ DO this way

Post # 4, @ zungeru : Welcome to LQ.

1) cd ns-allinone-2.34/ns-2.34/ ( Or whatever your version is ).
2) su ( or sudo 'make install', if you have Ubuntu.)
2a) make install : The binary 'ns' will be copied to /usr/local/bin/
... and ns will always be in your path.

The same can be done with nam : 'make install' will copy one file to
/usr/local/bin/ : 'nam'
