After updating rails from 3.2.3 to 3.2.14, and updating twitter-bootstrap-rails from 2.2.0 - 2.2.6 I'm getting this Less unrecognised input error:
Less::Error - Unrecognised input
(in /Users/andrew/rails/teebox_network/app/assets/stylesheets/bootstrap_and_overrides.css.less):
(gem) less-2.4.0/lib/less/parser.rb:74:in `block (2 levels) in parse'

The offending lines appear to be first 2 in bootstrap_and_overrides.css.less.

@import "twitter/bootstrap/responsive";

Googling suggested to downgrade to 2.2.0, however the error remains. I am running less-rails (2.4.2), sass-rails (3.2.6), therubyracer (0.12.0). If anyone needs any other gem versions just shout.
Do I have to update a critical gem to fix this issue?
I never got to the bottom of this issues, but as I didn't require access to the bootstrap mixins I reinstalled twitter-bootstrap-rails but ran the static stylesheets generator, so I wasn't using Less anymore.
rails generate bootstrap:install static
