Dear all,

while installing rubygems(1.2.0) in windows I am getting the below  
error.  
command used: ruby setup.rb

./lib/rubygems/spec\_fetcher.rb:1:in `require': no such file to load -- zlib (Loa dError) from ./lib/rubygems/spec_fetcher.rb:1 from ./lib/rubygems/source_index.rb:10:in`require’  
from ./lib/rubygems/source\_index.rb:10  
from ./lib/rubygems.rb:767:in `require' from ./lib/rubygems.rb:767 from setup.rb:22:in`require’  
from setup.rb:22

can anyone help me to solve this error.

I didn’t use ‘one click installer’ for ruby installation. bez I need to  
build ‘Ruby extensions’. so,  
I have installed ruby by ‘configure’ and ‘nmake’ commands.  
(within: c:/ruby/win32)  
now I am able to run the ruby extension program.

NOTE:  
I am using ruby version 1.8.6. with MSVC6

Thanks in advance.

It won’t work without zlib.
