My employer proxy just makes it difficult sometimes… So to install Ruby on Rails standalone
Do everything on http://rubyonrails.org/download until yu get to gem install rails
Then you need to download and install these packages from http://gemcutter.org
H:\Development\ruby>gem install rails
Successfully installed rake-0.8.7
Successfully installed activesupport-2.3.5
Successfully installed activerecord-2.3.5
Successfully installed rack-1.0.1
Successfully installed actionpack-2.3.5
Successfully installed actionmailer-2.3.5
Successfully installed activeresource-2.3.5
Successfully installed rails-2.3.5
8 gems installed
Thats it- not much but if you get this post it might have a valuable 5 mins off your time to rails and that could make all the difference
