1.2 rc2 installation problem

I'm following the instructions from the Rails main page:
gem install rails --source http://gems.rubyonrails.org
--include-dependencies
looks like it works OK, but every time it finishes and I say rails -v,
I get 1.1.6 instead of 1.2
Please help.
Thanks,
Yitzhak

The rails 1.2 release candidates use the internal designation of 1.1.6.nnnn, where nnnn increments as this moves forward. If you do a "rails -v" you will get 1.1.6. "gem list" should give you the real version #.
