How do I update/fix the SASS and Compass $PATH to work with grunt-contrib-compass

Question

I am trying to run grunt-contrib-compass, but running into this error:

Warning: Couldn't find the `compass` binary. Make sure it's installed and in your $PATH Use --force to continue.

I've run:

• sudo gem install compass
• sudo gem install sass
• sudo gem update --system

When I do gem list, I get:

compass (1.0.1) 
rails (4.1.6)
sass (3.4.5, 3.3.4)

ruby:

ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-darwin12.0]

Any suggestions or solutions on how to get grunt-contrib-compass working?
