[ns] Urgent: make error

[dm9]

Hi there,
 
I am very close to my project deadline and would really appreciate it if 
somone could help me 
with the following problem, 
I did a make on NS and got the errors below but the strange thing is that I 
never modified the 
files mentioned in the error so not sure how to solve this error. Could 
someone shed some light 
on this?? 
Thanks, 
Denis
