RHEL5 Getting The Rails Console Working 2

If you compile Ruby from scratch you may get this error when starting a script/console session:

`require': no such file to load -- readline (LoadError)

To solve this you need to install the readline ruby extension. Here I assume you are using the 1.8.7 Ruby.

sudo yum install ncurses-devel readline-devel
cd ~
mkdir src
cd src
wget ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.7-p72.tar.gz
tar zxvf ruby-1.8.7-p72.tar.gz
cd ruby-1.8.7-p72.tar.gz/ext/readline
ruby extconf.rb
make
sudo make install
