Yes I have run xcode-select --install. I am running Mac OS X 10.11.6 and Xcode 8.0. Just tried it again after running brew uninstall libxml2, same result.

Well, I upgraded to 10.12 (Sierra), did xcode-select --install, and it now builds. Hooray!

Following up on some initialization warning messages, replaced deprecated "username" with "defaultuser" and that seems to have fixed the problem
