Installing Ruby and RubyGems on Centos 5

I got around to setting up Ruby on our new Centos 5 server today and ran into a snag. I ran:

yum install ruby

And went on to installing rubygems. However in installing rubygems I got an error that rdoc was not installed. Now I don’t remember ever having to install RDoc on my mac so I did a quick google search. Seems that RDoc is part of the standard ruby install but my package didnt have it. So I uninstalled my my rpm and went on about compiling from source. However when I went to install rubygems this time I got an error about zlib. After another quick google search I realized that I had not installed the other ruby packages. So I killed my compiled source for ruby and reinstalled from rpms this time running


yum install -y ruby
yum install -y ruby-devel ruby-docs ruby-ri ruby-irb ruby-rdoc

Then my rubygems package installed correctly and I am on my way.
