Dear Sir/Madam,

I'm a PhD student doing research in IP/ATM networking.  I'd like to use
your ns2 network simulator for my work.  I just download all the
software as you instructed on
http://www-mash.cs.berkeley.edu/ns/ns-build.html.  And then Building it
>From Sources

    Fetch the source code as described above. 
    Unpack TclCL and ns source into the same top level directory. 
    Build TclCL: 
        cd into the ``TclCL directory'' (inappropriately called ``Tcl'';
we will fix this...) 
        run ./configure 
        run make 
    Build ns: 
        cd into the ns directory 
        run ./configure 
        run make 

But I can't run configure.  The message is as follows:

banyan{dpwu}117>ls
Tcl-1.0b2	ns-2.0b17
banyan{dpwu}118>cd Tcl-1.0b2
/home/kings/u1/dpwu/NS-2/ns/Tcl-1.0b2

Would you please help me with this?

Your help is highly appreciated.

Best regards,

Dapeng
