a problem in building ns-2.1b4

[Dapeng Wu <dpwu@fla.fujitsu.com>]

Dear all,

I had a problem in building ns-2.1b4 on Sun Ultra 30, Solaris 2.6.

First I downloaded all-in-once *.tar.gz file and unpacked them under my
home directory.  Then I successfully "make" under TclCL directory.  I
also successfully "configure" under ns directory.  But "make" (ns)
failed.

The last part of the message is as follows:

I could not find solution from the mailing list.  

Your help is highly appreciated.
