[ns] ns-2.29 installation problem: trace.c compilation error

[Salih ML]

Has any one encountered the following error while installing 2.29. I
 tried installing the 2.29.1 & 2.29.2 but still got the same error:

 make: *** [trace/trace.o] Error 1
 Ns make failed!

I checked the FAQ or ns-problems page but couldn't find the answer there.

I am trying to compile the code on a Ubuntu machine:
Linux xxxxx 2.6.22-14-generic #1 SMP Tue Feb 12 07:42:25 UTC 2008 i686 GNU/Linux

Thanks,
