Error installing Ruby with Rails on Server!

[AFTDESIGN]

I tried installing Ruby on Rails on my server and I got some errors.

I followed the install guide here: http://wiki.rubyonrails.com/rails/pages/HowtoInstallAndRunRubyOnRailsOnPlesk

I did install zlib before I did this.

Step 1: Install Ruby: Ok
Step 2: Install Gems: Error

Here is the log from the Gem install

As of RubyGems 0.8.0, library stubs are no longer needed.
Searching $LOAD_PATH for stubs to optionally delete (may take a while)...
...done.
No library stubs found.

I am running FC2 with Plesk 7.5.4

to me the key line looks like /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in `require__': no such file to load -- zlib (LoadError)

make sure you have zlib and zlib-devel installed

This shouldnt be necessary for most most people so you can skip this step. However, it may be wise to make sure you have zlib installed before you continue. If you do not have zlib then you will get an error message require__ when you try to install rails in step 3.
