[ns] ns error

["Id Uko" <ukoid@hotmail.com>]

Hi,
I experienced the following error when running the 'make' command, and would 
like to know if anyone has encountered this before.
I first created a new C++ file (application/agent) called Poisson.cc, then 
added Poisson.o to the Makefile, and also added variables to the 
ns-default.tcl script.  After doing this, I typed 'make' and it ended with 
the statement: "make: ***[ns] Error 1"
Below is the complete output (sorry, its quite long).

Could anyone please advice me on what to do? I am afraid my trace(.cc/.h) 
files may be corrupted?
Thanks in advance
