I am trying to run ActiveMerchant gem with old version of Rails (1.2.6). And if I require active_merchant gem i get this error:
config/boot.rb:17:Warning: Gem::SourceIndex#search support for String patterns is deprecated, use #find_name
/usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:280:in `activate': can't activate activesupport (>= 2.3.2, runtime) for ["activemerchant-1.4.2"], already activated activesupport-1.4.4 for ["rails-1.2.6"] (Gem::LoadError)
from /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:296:in `activate'

from /usr/local/lib/ruby/site_ruby/1.8/rubygems.rb:295:in `activate'
Upgrading rails is not possible. So what should I do? Maybe i can use older version of ActiveMerchant if so what version works with rails 1.2.6?
