Compass & Sass

Having problems with `compass watch`.

I keep getting this error `LoadError on line ["70"] of /Users/michaelprflores/.rvm/gems/ruby-2.1.1/gems/compass-0.12.6/lib/compass/commands/watch_project.rb: cannot load such file -- fssm
Run with --trace to see the full backtrace`

Not sure what to do, as I have to run `compass watch` over and over to get the sass to generate. Searched online for a solution to no avail.
