apt-get is suitable for Linux based Ubuntu machines; for MAC, try apt-get equivalent such as Brew

are you using a linux debian flavored system ?

if you are on Mac OS (iMac make me think so), you will not be able to use aptitude as it simply doesnt exist on Mac os.

may I advice you to go to http://www.macports.org/ which is kind of the same system (but based on Unix port)

I managed to final get a install up and running what a pain.

I am running an imac with mac os x version 10.6.6

i had to first run this command in the terminal. sudo port install ruby

ok great that then ran the install off ruby ok so after the install was complete i can the run this command.

rails new

which then created a project for me called "new" ok getting their.

next finding an editor to run rails- I installed netbeans seemed to be a good option.

next open new project and select ruby on rails application with existing sources, this then prompted me with the following error- that I don't have gems installed and to run this command.

gem install -v=2.3.5 rails

I have ran that command and got the following.

$ gem install -v=2.3.5 rails
WARNING:  Installing to ~/.gem since /Library/Ruby/Gems/1.8 and
      /usr/bin aren't both writable.
WARNING:  You don't have /Users/Ben/.gem/ruby/1.8/bin in your PATH,
      gem executables will not run.
Successfully installed rails-2.3.5
1 gem installed
Installing ri documentation for rails-2.3.5...
Installing RDoc documentation for rails-2.3.5...

ok so i then click ok on NetBeans and i am in with a project not sure whether gems is installed correctly tho, so gonna start learning ruby on rails now and ill report back with issues.

Hope this helps someone ;)
