Problem running check_ping

Hi
I'm running netsaint-0.0.7 on Red Hat Linux 7.3 (2.4.18-3). I think
check_ping is not functioning properly.
When i run comman :
 ../libexec/check_ping -H www.yahoo.com -w 100,20% -c 500,60% -p 10
I get this error message:  "You've got a big problem buddy! You need more
args!!! Cannot open pipe: "
Is there any problem in my syntex or it the problem with the plugin?
I had to rename /bin/ping to something else because of some unknown problem
during the compilation of both core modules and the plugins.
Thanks a lot,
Bikrant Neupane
