[ns] problem installing ns2.1b5

[Nipul Jayvant Shah <njshah@unity.ncsu.edu>]

Hi,
I have been trying to install ns-allinone-ns2.1b5. i used the file
ns-allinone-ns2.1b5a.tar.gz.
there is some problem with the ns make. I checked the ns mailing list
archive and found that a few other people also reported the same problem
but could find no mail resolving the issue. Can someone please help me
out?
below is the error i obtain.
thanks.

Nipul.
