I'm opening up the gem and trying to debug the issue: for your reference this is the parser options hash being generated:
{:filename=>"/Users/adam/Development/backchatio-marketing/app/assets/stylesheets/homepage.css.less", :line=>1, :paths=>["/Users/adam/Development/backchatio-marketing/app/assets/stylesheets", "/Users/adam/Development/backchatio-marketing/vendor/assets/stylesheets", "/Users/adam/.rvm/gems/ruby-1.9.2-p180/gems/less-rails-bootstrap-1.4.2/vendor/assets/stylesheets", "/Users/adam/.rvm/gems/ruby-1.9.2-p180/gems/less-rails-bootstrap-1.4.2/vendor/frameworks", "/Users/adam/Development/backchatio-marketing/app/assets/fonts", "/Users/adam/Development/backchatio-marketing/app/assets/images", "/Users/adam/Development/backchatio-marketing/app/assets/javascripts", "/Users/adam/Development/backchatio-marketing/app/assets/stylesheets", "/Users/adam/Development/backchatio-marketing/vendor/assets/stylesheets", "/Users/adam/.rvm/gems/ruby-1.9.2-p180/gems/jquery-rails-1.0.19/vendor/assets/javascripts", "/Users/adam/.rvm/gems/ruby-1.9.2-p180/gems/less-rails-bootstrap-1.4.2/vendor/assets/javascripts", "/Users/adam/.rvm/gems/ruby-1.9.2-p180/gems/less-rails-bootstrap-1.4.2/vendor/assets/stylesheets"]}
Opening the parser.js file and dumping out the tree.functions object's keys I find the following, which indicates they are there and available for use:
rgb,rgba,hsl,hsla,hue,saturation,lightness,alpha,saturate,desaturate,lighten,darken,fadein,fadeout,fade,spin,mix,greyscale,e,escape,%,round,argb,asset-path,asset-url,image-path,image-url,video-path,video-url,audio-path,audio-url,javascript-path,javascript-url,stylesheet-path,stylesheet-url,font-path,font-url,asset-data-url

I have drilled down to the Less-2.0.8 gem, into call.js to debug the try/catch there.
The resulting exception message is:
Error: This asset host cannot be computed without a request in scope. Remove the second argument to your asset_host Proc if you do not need the request.

The cause of the problem was the setting of asset_host to a Proc within rails. The aim of this was to switch HTTP/HTTPS on the CDN we use. This may be a common issue for others.
The cause:
config.action_controller.asset_host = Proc.new do |source, request|
method = request.ssl? ? "https" : "http"
"#{method}://foobar.cloudfront.net"
end
The solution:
Remove the CDN switch, or guard against the missing request argument.
config.action_controller.asset_host = Proc.new do |source, request=nil|
method = request != nil && request.ssl? ? "https" : "http"
"#{method}://foobar.cloudfront.net"
end
