To install/run less version 2 on mac:
 
1. Install Node.js
	Download a built copy from https://github.com/ajaxorg/node-builds.
	Alternately, o to http://nodejs.org/#download   (./configure, make, make install).
	
2. Download less from https://github.com/cloudhead/less.js/archives/master
 
3. Edit .bash_profile etc. to add node to your path, and lessc to NODE_PATH:
 
	export PATH=$PATH:/opt/less/bin
	export NODE_PATH=$NODE_PATH:/opt/less/lib
 
To compile all the files:
 
  $ cd dijit/themes/claro
  $ node compile.js
 
 
-------
Alternately, you can install less version 1, but I'd rather not use it for checked in files
since it breaks a part a lot of rules into multiple rules, causing spurious diffs.
 
To install on a mac:
  $ sudo gem install less
  
On Windows or Linux, make sure you have ruby and ruby-gems installed first.
If you need help installing ruby please check out ruby-lang.org for more details.
