Does the directory /usr/include/arpa _not_ exist, or just the
file inet.h in that directory? (If this is, your system include
files are incomplete.)

I also assume that "inet comma h" is a typo, and you've used
#include <arpa/inet.h> ("inet dot h") correctly. I also assume
you didn't modify the settings from where header files included
with #include <...> should be imported (cc -I).

Which FreeBSD version do you use? I'm using 7-STABLE here and
the file is present, it also contains the function prototype.

#define inet_aton               __inet_aton
int              inet_aton(const char *, struct in_addr *);

If you've installed the sources (at the correct version of the
OS you're using), you can find /usr/src/include/arpa with the
file, and you should be able to "make install" (not tested here)
from there to install arpa/inet.h into the correct location.
