発生している問題

ネットに出ている情報をいろいろ試してみましたが、zipruby が入りません。
１．gem install zipruby
ネットに出ている通り

C:\>gem install zipruby 
Building native extensions.  This could take a while... 
ERROR:  Error installing zipruby: 
        ERROR: Failed to build gem native extension. 

C:/Ruby/bin/ruby.exe extconf.rb 
checking for zlib.h... no 
*** extconf.rb failed *** 
Could not create Makefile due to some reason, probably lack of 
necessary libraries and/or headers.  Check the mkmf.log file for more 
details.  You may need configuration options. 

Provided configuration options: 
        --with-opt-dir 
        --without-opt-dir 
        --with-opt-include 
        --without-opt-include=${opt-dir}/include 
        --with-opt-lib 
        --without-opt-lib=${opt-dir}/lib 
        --with-make-prog 
        --without-make-prog 
        --srcdir=. 
        --curdir 
        --ruby=C:/Ruby/bin/ruby 

I am an extreme newbie to building C extensions, so my Googling for 
details on the zlib library did not do me much good.  Any suggestions 
for how to proceed?

２．gem install zipruby1.9 --platform mswin32
ネットで紹介されている方法ですが、

C:\>gem install zipruby1.9 --platform mswin32
ERROR: Could not find a valid gem 'zipruby1.9' (>= 0) in any repository
ERROR: Possible alternatives: zipruby1.9

となり入りません。

３．zlib.h を入れて(zlib-1.2.3-lib.zip) gem install zipruby
