You are running a wrong version of activesupport (RubyGem version error: activesupport(1.4.2 not = 2.0.2) (Gem::LoadError))

Have you tried "gem install activesupport" ?

I should look like this:

actionmailer (2.0.2) actionpack (2.0.2) actionwebservice (1.2.6) activerecord (2.0.2) activeresource (2.0.2) activesupport (2.0.2)

Try this:

gem update --system gem update --source http://gems.rubyonrails.org

3

try

gem install activeresource --source http://gems.rubyonrails.org
