This is the real problem. You need to install the glibc and linux kernel 
header files, and they must be readable to the user compiling the 
program. In the header files there are typedef statements, which 
identify various types of variables so that gcc knows their width. 
Without these statements you get warnings of the type shown below.
What does 'ls -l /usr/include/{getopt,linux/if_ether,features}.h' say on 
your system?
