Cannot install on linux

I'm trying to follow this https://steemit.com/steemhelp/@nextgencrypto/basic-mining-instructions--ubuntu-15
I'm on Elementary OS Freya. I successfully installed boost 1.57 using this guede: http://shortrecipes.blogspot.si/2015/02/ubuntu-1404-install-boost-157.html

But I'm still getting this ugly error. I must be missing something.. :(
