Using less (2.2.1) raises an error requiring therubyracer (can't install therubyracer on windows)

I've been working to get twitter-bootstrap-rails gem working on my windows machine and ran into an error attempting to install 'therubyracer' gem which is a dependency of older version of the less gem.

I think upgraded to less 2.2.1 which is not dependent on therubyracer however in spite of that it seems to think I still need therubyracer installed. Here is the output of the error I get when I try to start my rails server 'rails s'.

$ rails s
[WARNING] Please install gem 'therubyracer' to use Less.
