gem install nokogiri on Windows XP

[Kee Kee Mu]

I issue the command "gem install nokogiri" on Windows XP console. I use
Cygwin.
And, I got the following errors, please help.

$ gem install nokogiri

I believe the error message is pretty clear.

You need to install libxml2 in your cygwin installation to be able to install nokogiri. See the installation document for other dependencies.

Try adding libxml2 to cygwin using the cygwin's setup.exe. You may
also have to add a few other libraries along the way but I'm sure you
will be notified of these as well.
