Installing Ruby On Rails on Ubuntu with rmagick

My laptop hard disk drive (it was a fujitsu drive on an HP Pavilion nobebook pc) was gone withing just two months of purchase. Later I got the replacement but, I had to spent another to prepare rails stack again :(
Anyway, here is the recipe for Ubuntu 7.10
$ sudo apt-get install ruby irb ri rdoc ruby1.8-dev libopenssl-ruby1.8 build-essential
$ wget
$ tar xzvf rubygems-1.0.1.tgz
$ cd rubygems-1.0.1
$ sudo ruby setup.rb
$ sudo ln -s /usr/bin/gem1.8 /usr/bin/gem
$ sudo gem update --system
$ sudo gem install rails
$ sudo gem install mongrel

I couldn't install rmagick on the first place. Because building rmagick (v2.3.0) requires ImageMagick version 3.0 or greater but current Ubuntu repository provides only v2.6 (by the time I wrote this). So, I had to install from the source. Thanks to Emmannual for this suggestion.
Remove ImageMagick, if you have already installed
sudo apt-get remove imagemagick

Now download, compile and install from the ImageMagick source
$ tar xvvzf ImageMagick.tar.gz
$ cd ImageMagick
$ ./configure –prefix=/usr
$ make
$ sudo make install
$ sudo gem install rmagick

Or alternatively, you can download binary of ImageMagick-dev from debian repo

$ sudo apt-get install libmagick9-dev
$ sudo gem install rmagick

One more step. Install all necessary gems that are required by the project you are working. Like, our current rails project uses the gem 'memcache-client'. So, I ran the following
$ sudo apt-get install memcached
$ sudo gem install memcache-client
