Are you trying to install Sage 6.2 (as your log seems to indicate)? That is extremely old. Try with a fresh source installation: either http://www.sagemath.org/download-source.html for stable source or http://www.sagemath.org/download-latest.html for the latest development version. Also, do you have the Xcode command-line tools installed? Run "xcode-select -install" from the terminal.
Finally, as Dima says, Sage won't build as is on OS X High Sierra, but the problems should come later in the installation process.
