[ns] a correction to configure TCL DEBUG

[Sudhindra Suresh Bengeri <ssbenger@unity.ncsu.edu>]

Hi ns-users,

I was trying to install tcl-debug package and reconfigure ns:

by adding the --with-tcldebug=path argument, but it was not able to find 
libtcldbg.a , this was because the libtcldbg.a is kept in the 

'tcldebugpath'/lib/tcldbg1.9 directory and the 

ns-allinone-2.1b6/ns-2.1b6/configure file does not look for libtcldbg.a in
that directory: 

Here's the change that's required for ns-allinone-2.1b6/ns-2.1b6/configure

TCLDEBUG_PATH_D="$d \
                $d/lib \
                $d/../lib \
                $d/lib/tcldbg1.9 \   <== this was the missing line.
                "

I was trying to configure on a SunOS 5.6 box. If the problem was reported
and fixed I apologize this redundant message.

Regards,
Sudhin.
