Yep I see your problem. One thing you could try, *note* I've not tried this so it may or may not be efficient, when you compile the Nagios plugins, add the following directive to ./configure:
--with-ping-command="/bin/ping -s 0 -n -U -w %d -c %d %s" (ie. add the "-s 0" parameter to the ping plugin). In theory this should compile check_ping with the near-0-byte ping command I ran manually earlier. In practice, I don't know how you could check it's OK (unless you can monitor bandwidth manually, or notice really low RTAs compared to the 64-byte command.) Hope this helps some more!
