help needed urgently

[Rachad Abdallah <ietflist.rachad@icn.siemens.de>]

Hello !

I am trying to install the ns-allinone-2.1b5 to use it in a project at
Siemens AG. While running the command ./install on a linux red hat 5.1
I get the following messages ... Please note that I am a new user of linux
and ns. Your help is highly appreciated and needed as soon as possible. My
guess is that there are some packages missing on my machine but I don't
know which. thank you again.
