Hi all -

I am trying to get Mongrel installed on an old box but am having  
troubles. The box is running Ubuntu and I have installed the latest  
ruby, rails, and gems as far as I can tell. This is what I am  
getting:

mongrel1@mongrel1:~$ sudo gem install mongrel  
/usr/local/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:27:in  
`gem_original_require': no such file to load -- zlib (LoadError) from /usr/local/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:27:in`require’  
from /usr/local/lib/ruby/site\_ruby/1.8/rubygems/package.rb:9  
from /usr/local/lib/ruby/site\_ruby/1.8/rubygems/  
custom\_require.rb:27:in `gem_original_require' from /usr/local/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:27:in`require’  
from /usr/local/lib/ruby/site\_ruby/1.8/rubygems/builder.rb:7  
from /usr/local/lib/ruby/site\_ruby/1.8/rubygems/  
custom\_require.rb:27:in `gem_original_require' from /usr/local/lib/ruby/site_ruby/1.8/rubygems/ custom_require.rb:27:in`require’  
from /usr/local/lib/ruby/site\_ruby/1.8/rubygems.rb:93:in  
`manage\_gems’  
from /usr/local/bin/gem:10  
mongrel1@mongrel1:~$

Any ideas? Any help greatly appreciated.

-Adam

It looks like you might be missing one or more of the following  
packages, installable with “sudo apt-get install (package name)”:

build-essential  
libzlib-ruby  
zlib1g  
zlib1g-dev
