[hassanh@VNET.IBM.COM]

  Hi all ,
        This is Hany Hassan , MSC student at Cairo Univ.

     I tried to bulid ns-2.0b17 on Linux 2.0.0 .
     After finishing compilation and during linking the following error
     was issued :

      /usr/i486-linux/bin/ld :

       cannot open -ldld: No such file or directory
       The complete ouput is listed at the end of the mail.
       What did I miss ?

       Thanks in advance ,
       Best Regards
       Hany Hassan
