unable to build sassc

[ligio90]

When I try to install sassc on my Ubuntu computer (using gem install sassc -v '2.0.0'), it is unable to build. How can I fix it, thanks.

`Building native extensions. This could take a while...

Hello,

Think this is probably an issue for https://github.com/sass/sassc-ruby rather than here
