error sqlite3 requires Ruby version >= 1.9.1

I've used sqlite before. My friend sent me a skeleton rails app that I am trying to run.

When I try to do "rails server" or "thin start" it says

Could not find sqlite3-0.1.1 in any of the sources"

I tried to do bundle install but it throws this error:

Installing sqlite3 (0.1.1) /Library/Ruby/Site/1.8/rubygems/installer.rb:364:in ensure_required_ruby_version_met': sqlite3 requires Ruby version >= 1.9.1.

I don't know why it's trying to look in the 1.8 folder with Ruby 1.9.2 installed.

What am I doing wrong?

Your bundle command is pointing to your system Ruby, type the following to see which Ruby your Bundler is pointed to: head -1 $(which bundle) Either that needs to be pointed at the Ruby you want to use and/or you need to use the Ruby you want to use to install the Bundler gem (which will put the right shebang line in your bundle executable).
