Subject: error installing using rubygem

I am doing a fresh install. I have installed

OS Redhat Enterprise

Ruby 1.8.6 (from Source)

rubygems versions 1.0.1 (from Source)

when I run the following to install rails:

gem install rails --include-dependencies

I get the following error:

[root@localhost rubygems-1.0.1]# gem install rails --include-
dependencies

I have searched google up and down but cannot find a answer. Any help
will be appreciated.
