windows net/ping load error

[Athreya Vc]

Hi I have installed ruby on Windows

C:\Ruby192\bin>ruby.exe -v
ruby 1.9.2p0 (2010-08-18) [i386-mingw32]

C:\Ruby192\bin>

Then I have installed the below gems

C:\Ruby192\bin>gem list --local

*** LOCAL GEMS ***

hoe (2.8.0)
json_pure (1.4.6)
minitest (1.6.0)
net-ping (1.3.7)
rake (0.8.7)
rdoc (2.5.8)
rubyforge (2.0.4)
test-unit (2.1.2)

But net/ping is giving an error while loading

irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require 'net/ping'
