Step 1: First step is to install some inportant packages that are recured,
sudo apt-get -y install build-essential libssl-dev libreadline5-dev zlib1g-dev
Step 2: Install ruby
RUBY="ruby-1.8.6-p111" //Current stable version
wget ftp://ftp.ruby-lang.org/pub/ruby/1.8/$RUBY.tar.gz
tar xzf $RUBY.tar.gz cd $RUBY
./configure --prefix=/usr/local --with-openssl-dir=/usr --with-readline-dir=/usr –with-zlib-dir=/usr
make clean
make
make install
make install-doc
make clean will clear any make files in that folder, previosly created that was configured without right options Checking whether ruby is installed properly
ruby -ropenssl -rzlib -rreadline -e "puts :success"
Step 3: Install Gem

RUBYGEMS="rubygems-1.0.1" //Current stable version
wget http://rubyforge.org/frs/download.php/29548/$RUBYGEMS.tgz
tar xzf $RUBYGEMS.tgz
cd $RUBYGEMS
/usr/local/bin/ruby setup.rb

Main Errors during Installation:
Error 1:
/usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require’: no such file to load — zlib (LoadError)
using the following step for configuring ruby, that is before make, will remove this problem
./configure --prefix=/usr/local --with-openssl-dir=/usr --with-readline-dir=/usr –with-zlib-dir=/usr
Error 2:
no such file to load — mysql
undefined symbol: rb_Digest_MD5_Init – /usr/local/lib/ruby/1.8/i686-linux/digest/md5.so (LoadError)
