problems about installing ns-2

[Yung-Szu Tu <yungszu@ee.ucla.edu>]

Hi,
    I am a new user of ns-2. After I downloaded the all-in-one package
, run the install script, add the following in my .cshrc


set path=($path /w/ee.0/rubin/yungszu/ee233c/ns-allinone-2.1b5/bin)

setenv LD_LIBRARY_PATH /w/ee.0/rubin/yungszu/ee233c/ns-allinone-2.1b5/otcl-1.0a4

I try to run the demos shown in your mannual.

ns fq.tcl

But the error message is as followed.
athens% ns fq.tcl
application-specific initialization failed: Can't find a usable init.tcl
in the
    /usr/local/lib/tcl7.5 /usr/apps/lib/tcl7.5
/w/ee.0/rubin/yungszu/tcl7.5/liby
This probably means that Tcl wasn't installed properly.

couldn't read file "fq.tcl": no such file or directory


How to deal with this problem?

Thanks

Sincerely, 
Yung-Szu Tu
