when install nicstat, I got the following errors:
gcc -O3 -m32    nicstat.c   -o nicstat
In file included from /usr/include/features.h:385,
                 from /usr/include/stdio.h:28,
                 from nicstat.c:33:
/usr/include/gnu/stubs.h:7:27: error: gnu/stubs-32.h: No such file or directory
make: *** [nicstat] Error 1

On centos, the following command can resolve this issue:
yum install glibc-devel.i686
--full command  yum install glibc-devel-2.12-1.192.el6.i686
