These dependencies are needed in order to implement multi website.
According to this, we need the following dependencies:

• apt:
  • ruby-compass
• gem:
  • compass
  • bootstrap-sass

In order to install those dependencies, we also need:

• apt:
  • ruby-dev, fixes:
    
  • autoconf, fixes:
    
  • automake, fixes:
    
  • libtool, fixes:

After all these dependencies were installed, I was able to install compass and bootstrap-sass using gem.
