Could not find linecache-0.43 in any of the sources

Hi Everyone,

I have updated to rails 3. When I try to run my rails server by doing this command: "rails server".

I get this error:

"Could not find linecache-0.43 in any of the sources. Try running 'bundle install'.

I try bundle install and I get another error saying

installing linechaceh <0.43> with native extensions C:/Ruby192/lib/ ruby/1.9.1/rubygems/installer.rb:483:in 'rescue in block in build_extensions': ERROR: Failed to build gem native extension. <Gem::Installer::ExtensionBuildError>

C:/Ruby192/bin/ruby.exe extconf.rb can't handle 1.9.x yet ***extconf.rb failed*** Could not create Makefile due to some reason, probably lack of neccessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.

Provided configuration options: (list of all options)

could someone help me?
