Installing Ruby 1.8.6 from Source on Ubuntu

Installing Ruby from source is my preferred method, although in Ubuntu Feisty you can supposedly install it with apt-get install ruby
now. Here’s the essential packages needed to get a source build working right though and the process I just went through:
sudo apt-get install build-essential
sudo apt-get install libreadline-dev
sudo apt-get install libz-dev (this is necessary for RubyGems to install - amongst other things)
wget ftp://ftp.ruby-lang.org/pub/ruby/ruby-1.8.6.tar.gz
tar xzvf ruby-1.8.6.tar.gz
cd ruby-1.8.6
./configure
make
make install
And to install RubyGems..
wget http://rubyforge.org/frs/download.php/17190/rubygems-0.9.2.tgz
tar xzvf rubygems-0.9.2.tgz
cd rubygems-0.9.2
ruby setup.rb

Install ruby 1.9 on Windows using zip binary

Update:  This post is outdated. All in one installer for 1.9
is ready now, you should use it if you need 1.9 on windows. Get it here
http://rubyforge.org/frs/?group_id=167
Ruby has “all-in-one” installer for Windows, but it is outdated. As
of May 2009, Ruby 1.9.1 is released, the installer is still 1.8.6. If
you want the latest version, you need the zip package. But the zip
package is missing zlib.dll, libeay32.dll, ssleay32.dll and readline.dll
. Here is how to install it on windows.
Download the file
First you download the 1.9 package from http://www.ruby-lang.org/en/downloads/
Choose “Ruby 1.9 xxx binary” instead of “Ruby xxx Installer”.
Install it
Just Unpack the zip to c:\ruby.
Then add c:\ruby\bin to windows PATH.
Open a windows command console and type
gem update --system
Oops, it is broken! The binary is missing some dll files.
Let us fix it
zlib
Download zlib windows binary from
http://gnuwin32.sourceforge.net/ ......
