Line 202 is contained within the following #ifdef structure:

#ifdef ON_DARWIN
        if ((ip = libnet_name_resolve((unsigned char*)ipaddr, 1)) == -1UL) {
#else
        if ((ip = libnet_name_resolve(ipaddr, 1)) == -1UL) {
#endif
                cl_log(LOG_ERR, "Cannot resolve IP address [%s]", ipaddr);
                unlink(pidfilename);
                return EXIT_FAILURE;
        }

        l = libnet_open_link_interface(device, errbuf);
        if (!l) {
                cl_log(LOG_ERR, "libnet_open_link_interface on %s: %s"
                ,       device, errbuf);
                unlink(pidfilename);
                return EXIT_FAILURE;
        }
#elif defined(HAVE_LIBNET_1_1_API)
        if ((l=libnet_init(LIBNET_LINK, device, errbuf)) == NULL) {
                cl_log(LOG_ERR, "libnet_init failure on %s: %s", device, errbuf\
);
                unlink(pidfilename);
                return EXIT_FAILURE;
        }
#ifdef ON_DARWIN
        if ((signed)(ip = libnet_name2addr4(l, (unsigned char *)ipaddr, 1)) == \
-1) {
#else
        if ((signed)(ip = libnet_name2addr4(l, ipaddr, 1)) == -1) {
#endif 

Could you please be a little more specific as to what alternate version you're referring to and what change needs to be made?

Later compilers differentiate between char* and unsigned char* If you go to that part of the file you should see the alternate version there (which I use on OSX).  You'll probably need to make the same sort of change.
