I got ruby installed.

I got rubygems installed, and these messages confirmed success:

RubyGems 1.3.6 installed

RubyGems installed the following executables:  
/usr/local/bin/gem

but when I run gem list, I get this:

/usr/local/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:31:in  
`gem_original_require': no such file to load -- zlib (LoadError) from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in`require’
