Please give it a try before you assume it won't work? Tell me what platform you're on and follow the three sequential cli commands I provided, and if it doesn't compile I'll be glad to look at your error message and get it going in the right direction.
You're missing the trees for the forest, friend. I know how to troubleshoot this stuff. I wouldn't expect some random schmo who's just learning ubuntu for the first time to be able to.
This, "just run these three commands" attitude is exactly the reason why these curl|sh "installers" have become popular.
