Note, I did manage to get a gatsby new site (empty) running. It appears to be some of the dependencies that are failing.

Expected behavior

I get a new site.

Steps to reproduce

1. Follow gatsby tutorial 1
2. Type gatsby new icar2 https://github.com/Vagr9K/gatsby-material-starter into console.

Thank you!

Hang on! Please don't spend any time on this issue just yet; I don't have g++ installed. Let me work out of for now; understand why and I'll update this thread and docs (better specification in pre-requisites I imagine).
